  • How to protect Welders from hazardous fumes
    2019 HSE Welding Fumes Change in regulation - have you got it covered? Metal Fabrication Supplies offer four simple steps to help you protect the workforce from those hazardous welding fumes! One single welder can produce up to 40 grams of fume every hour. This means that over a 12-month period, a welder could possibly produce about 35-70 kilograms per year. Welding fumes are generally made up of particles formed from the filler material and the actual material being welded. The fumes are produced when a metal is heated to above its boiling point, the vapours then condense when they reach the cooler atmosphere. Whilst cooling they take the form of very fine particulates, many of these can be in the nanoparticle range and can remain in the air for up to 24 hours.

  • Welding without adequate eye protection
    Welding without adequate eye protection means more than 365,000 workers suffer with eye-injuries - that is nearly 1,400 a day! Eye injuries make up one quarter of all welding injuries and they cost employers more than £366 million annually. Welding injuries to the face and eyes generally fall into four categories, Hot metal slag burns, Injuries from flying particles, Exposure to ultraviolet (UV) radiation, Exposure to irritating fumes, vapours, and chemicals

  • What is Hand Arm Vibration Syndrome?
    Hand Arm Vibration Syndrome (HAVS) is a widespread recognised industrial disease which is affecting thousands of workers every day. It is a disorder which affects the blood vessels, nerves, muscles and joints of the hand, wrist and arm. It is normally caused by excessive, long-term exposure to working with tools that vibrate. 1 in 10 people who work regularly with vibrating tools may develop HAVS.

  • What to consider when purchasing a MIG Welding Torch
    When it comes to purchasing a MIG Welding Torch and the on-going consumables, it can often be after a great deal of thought. However, the wrong choice could have a profound effect on your welding process and could affect the welding equipment’s performance. MIG Welding Torches are the most handled piece of equipment during the MIG welding process and they are exposed to the worst working environments and abuse. This can often have a significant impact on the weld quality, productivity and increase the operator’s downtime. It is often thought that all MIG Welding Torches are the same, so price often becomes a deciding factor when welders considering purchasing a new MIG Welding Torch.

  • What is the difference between a 4 1/2” Angle Grinder & 5” Angle Grinder?
    The most common small angle grinder purchased in the UK is the 4 1/2” Angle Grinder. 4 1/2” Angle Grinders are suitable for light duty tasks, or when access could be a problem. Due to the smaller size a 4 1/2” Angle Grinder will never be as productive as a 5” Angle Grinder. 4 1/2” Angle Grinders are also more compact which makes them easier to grip and manoeuvre for some applications. 4 1/2” are purchased more often because they appear to have a lower initial cost when compared to a 5” Angle Grinder.

  • Why Metabo LiHD Cordless Tools are a Viable Alternative to Corded
    Since the introduction of the revolutionary Metabo Li-HD batteries, Metabo are continuing to follow the vision of a cordless construction site, striving to deliver a cord free safer working environment, and giving users ever more freedom. Over the past few years Metabo has been at the forefront in cordless development. They were the first cordless power tool manufacturer to launch a 4.0Ah then 5.0AH battery packs, and more recently were the first to move to LiHD cells. The new LiHD batteries offer greater flexibility, reliability and performance, currently making Metabo the only manufacturer of 18v cordless tools to cover an entire performance range of tools, from 400 to 2,400 Watt.

  • From Twist Drills to Rotabroach Cutters - The Evolution of Hole Making
    Stephen A. Morse of East Bridgewater, Massachusetts invented the twist drill in 1861. They have remained the most common way of producing holes, up to this present day. The early drill bits were manufactured by producing two grooves opposite sides to each other in a round bar, the bar was then twisted to produce the flutes. Nowadays, the flutes of the drill bit are ground into the bar by rotating and passing the bar over a grind wheel which precision grinds the flutes.

  • What is the best respirator for welding?
    When asking ‘what is the best respirator for welding and metal cutting?’ a number of factors need to be considered. But first we’ll give a bit of background. The fumes given off during welding or a hot cutting process is a varying mixture of airborne gases and very fine particles. Welding fumes are formed when the metal is heated above its boiling point and vapours condense in the atmosphere creating very fine, solid particulates. These particulates can be a mixture of metallic oxides, silicates and fluorides. If inhaled, they may cause ill health and are often dismissed or not correctly protected against. Welding fumes are recognised internationally and are classified as a possibly carcinogenic to humans should we be exposed to them for long or even regular short periods of time.
