Welding Fume Safety

Health and safety is critical where industrial processes expose employees to dust, powders, smoke or fumes.

Welding fume is clearly recognised as a contributor of respiratory issues and long-term lung disease.
The good news is that welding fume can be easily captured and removed from the workplace to protect the operators breathing zone and prevent fume spreading throughout the working environment.

“The most successful method of extracting any dust or fume is at the point of source,” comments Mr Cameron Prestidge from Egmont Air. “It sounds simple, but the challenge is a design that achieves this without interfering or restricting the process of work in operation.”

It is important that the correct airflows and capture designs are specified. In this way the toxic or nuisance pollutants are removed to protect the operators without creating nuisance draughts that cause porosity and poor weld quality.

Capturing toxic particles ‘at source’ also offers other benefits in terms of workshop cleanliness, clean-air compliance and employee well-being, to create a workplace that provides a more productive environment.

Egmont Air offers many devices such as articulating arms, fume cupboards, down-draught benches, air cleaners, centralised vacuum systems, specialised hoods and other proprietary equipment so that a solution can be specified for each individual application.

A huge range of filtration and dust collectors allows the correct type of dust collector to be matched for each pollutant. High-efficiency filtration provides clean-air discharge to exceed environmental regulations, in some cases allowing purified air to be returned to the working environment.

Automatic cleaning by a reverse-pulse of compressed air maintains the filters in optimum working condition and reduces the level of maintenance and monitoring required, compared to other types of cleaning.

A range of small and large dust collectors are available off-the-shelf to suit single machine extraction for individual saws and grinders etc, or large multiple-station systems are available that can be connected to a centralised ducting network for plasma cutting, welding, batch mixing, screening and other similar processes.

Use of wire brushes in stainless steel welding

It is a well-known fact that proper cleaning of work pieces prior and after the welding process is essential for getting welds with good appearance and mechanical properties. In many applications manual cleaning with a stainless steel wire brush can be the best method.

The finished welds and surrounding parent material may be contaminated by weld spatter and oxide films. In certain applications it may be also necessary to clean the weld material and to polish the weld area. Again mechanical brushing with a stainless steel brush is an excellent option.

Stainless steel wire brushes (especially 316 grade) are much less likely to produce sparks than the standard grinding methods. This reduces the risk of injury or fire.

Due to the risk of contamination always store the brushes and other tools used for stainless steel applications separately. Also avoid using them in ferrous applications.

All Dixbro wire brushes are made with 316 stainless steel and they have usually green colour, however always check before using them.
Dixbro has been a leading brand of industrial wire brushes in New Zealand and Australia for over 50 years. Your engineering supplier will be happy to discuss your needs with you.

Food safety is a top priority

There has been a few food product recalls of late published in media as well as the settling of a high profile food contamination case. 

A recent report undertaken by international firm PwC also lists the top 10 food supply and integrity issues and near the top of the list is scandals and increasing scrutiny and rising food standards. With this in mind EQM’s Anthony Bloxham says it’s important to ensure you have the highest of quality and performing food equipment and at the top of the list is stainless steel. 

“They don’t harbour bacteria, are more hardwearing and can withstand humidity, moisture and corrosion. They really lift the performance of the entire production process,” he says. 

EQM stocks the ABI range of stainless steel gear motors which are perfect for the food processing sector as they can withstand high water pressure (1400PSI) and incredibly hot water (maximum 80°C). 

“This is important when it comes to food hygiene and the sterilisation of equipment as they can tolerate extreme changes in humidity and temperature.” 

Stainless Steel gear boxes have been the perfect solution to stopping an ongoing corrosion issue with a meat plant’s gearboxes. Constant cleans and wash downs led to the plant having to regularly replace gear boxes to keep operating and meet hygiene standards. 

Not only did the stainless steel gearbox provide the best solution to prevent corrosion but as it has a universal mount – it was able to fit perfectly into the same place as the inferior existing gear box. 

A chicken processing plant is plucking more chickens without worrying about production downtime from breakdowns to motors and gearboxes since installing the EQMi stainless steel motors. The motor casing is smooth, can be easily cleaned and with extra special seals it resists the risk of water penetrating into the motor.

European quality solutions to workspace dust and fume problems at minimum cost

Many companies have air quality issues dotted around the site that are now being picked up by regulatory authorities. Fume arms are one of the simplest, quickest and economical ways to solve a polluted air issue, due to their effectiveness in the way they can capture and contain the impurities close to where they are being generated.

Workshops around the country have relied upon a fan in the roof or open doors either end of the workshop so the wind can provide the ‘extraction’. But this means you remove the fumes once the operator has already breathed them in and they then exit the building via the breathing space of all the other employees downwind. It can also result in a very cold place to work during the winter months, leading to more staff absence and resulting loss in productivity.

This was never common sense and is no longer acceptable practice. 

The installation of a fume arm, pulled into position so that the pollutants are captured almost immediately, is the most efficient way to improve working conditions and these can either be installed with their own fan or, if the existing extract system is powerful enough, they can be incorporated into the main system.

Fume arms being nearer the problem, means they require a lot less air through them than a large hood above the worker. They also require smaller duct size, a smaller fan and end in smaller power bills. In fact a ‘hood solution’ means, once again, the welder or bag filler has already been exposed to the fumes prior to removal above his head, the opposite of what you’re trying to achieve. 

“Avoiding welding fumes travelling or mixing with good air is key,” says Matt Darnbrough, NZ Duct+Flex South Island Sales Manager, “and our in house installation team are able to provide solutions very efficiently. Dealing with the issues where the fumes are generated really does sort out the environmental air quality for all staff.

“Having our own install employees and Engineering Manager instead of using contractor’s saves the customer time and ensures a fully compliant result,” comments Geoff Ebdon, Sales Manager for NZ Duct+Flex. “Also, despite pre install inspections and site plans being prepared, things always change slightly when the final install starts: for example people forget that there is a beam in the way or the exit through the wall has had to move! Having our own staff installing means they have a vested interest in doing the job once, correctly and to the standards, ensuring compliance.”

North Canterbury electricity lines company, MainPower New Zealand Limited have just purchased a Fume Arm (160mm diameter with three-metre reach) with a small quantity of Liplock® galvanised modular ducting, to connect the Fume Arm to a venting system already running in their Rangiora workshop. 

“Safety and health is intrinsic in everything that MainPower does. Our goal is for everyone that works for us to go home safe, healthy and well,” says MainPower’s Safety Health Environment & Quality Manager Dayle Parris. “We recognised the NZ Duct fume arm as a further improvement on our existing system.”

“Our Fume Arms are proving very popular due to the external hinging so there is less restriction to the airflow inside the tube,” confirms Geoff Ebdon. “Also, if hinging is on the inside, then all the muck passes over the hinge and they get damaged or jam up and you have to take the arm apart to clean them. We also have metal hoods and sleeves not plastic, with an all round grab handle and dampener so the hoods are easily manoeuvred to the best position – meaning the welder will use them!”

Quality powder coated steel tubes made in Europe and a full range of sizes from 75mm one metre reach, up to 160mm four metre reach are in stock available for immediate delivery.

Digital measuring equipment for highly accurate modelling – Dotmar Engineering Plastics

New Zealand manufacturing Icon, Dotmar Engineering Plastics have increased their support to manufacturers and component designers throughout New Zealand.

When business are faced with premature equipment obsolescence or poor functionality due to worn or broken metal and plastic parts Dotmar can rescue the day.

A recent acquisition is digital measuring equipment from Kreon Technology USA. This very accurate piece of equipment removes all doubt when there is a requirement to measure and model a component.

Curves, tapers, radii, 3D shapes are easily measured and converted to solid files. 

Older equipment may often contain obsolete parts and when these break there is no option but to remake them, to do this first they have to be accurately measured and drawn. Often when the worn, damaged or prototype components have to be copied it is discovered any drawings are possibly long gone or the original manufacturer closed up years ago and the only references are existing parts. 

A regular request is the measurement of components on site, the Kreon is able to be taken to site anywhere in New Zealand and set up to measure parts insitu. The benefits are that the Engineer not only gets accurate measurements to +/-0.01mm but the machine downtime is greatly reduced allowing quick return to production. Examples of where this feature has been utilised include bottling plants, paper mills, mines and anywhere there are large parts that may be difficult to move or transport, fragile or integral to ongoing production. The Kreon has no size limits to what can be measured.

Tool designers who need an accurate drawing file of existing components to begin manufacturing injection, thermoforming or blow moulded dies are finding this technology invaluable in reducing the build phase time by days and weeks whilst still ensuring accuracy is maintained.

The complete measuring service includes providing a solid file in a range of formats from which to manufacture the replacement or copied component.

Dotmar throughout New Zealand specialise in the manufacture of multi axis, low volume, machined plastic components for marine, production, aeronautical, packaging and associated industries.
