The MIG process is a versatile welding technique which is suitable for both thin sheet and thick section components. It is capable of high productivity but the quality of welds can be called into question. To achieve satisfactory welds, welders must have a good...read more
Using an inert gas shield instead of a slag to protect the weld pool, this technology is a highly attractive alternative to gas and manual metal arc welding and has played a major role in the acceptance of high quality welding in critical applications. Essential...read more
Fumes are airborne particles small enough to be inhaled and are produced in all welding and cutting operations. They are a mixture of: gases from the surrounding air, shielding gas, metallic elements - from parent metals, coatings and welding fluxes, which are...read more
A small but stout 15 kg unit, the ESAB Renegade™ ES 300i is a ground-breaking combination of PORTABILITY and POWER. It has the highest power to weight ratio in its class designed to virtually go anywhere on the job site. Renegade ES 300i handles single- and...read more
Types of electrodes and their compositions Many types of manual metal arc (MMA) electrodes are available on the market. Depending on the main constituent of their flux, they are grouped into three categories: cellulosic, rutile and basic. All electrodes consist of a...read more
To confirm that a weld has been made to specification it is usually required to measure and often document the parameters that have been used. For arc welding the main parameters are as follows: Welding current Arc voltage Travel speed These parameters can be used to...read more
