The Cigweld Transmig 185 Ultra features an impressive AUTO SET function that allows the user to weld like a Pro with no previous welding experience necessary.read more
Best practice in design is not simply a matter of deciding on the appropriate weld size or component thickness capable of carrying the service loads. There are many aspects of designing a welded component that need to be considered in addition to calculating permissible stresses.read more
Low alloy steels are used extensively for high-temperature applications in power plants and the petrochemical industries but, while they have good weldability, they also present distinct challenges when they have been aged through service. This is because these steels, when service aged, are particularly susceptible to embrittlement and cracking.read more
In TIG welding, the arc burns between the workpiece and a non-consumable tungsten electrode. To protect the electrode and molten pool from oxidation, both are shielded with an inert gas, generally argon. This welding process is suitable for all fusion-weldable metals....read more
Gas metal arc brazing (GMA brazing) is an alternative method for joining primarily thin sheets that have been coated for corrosion protection. This method offers considerable advantages over GMA welding since an alloy metal with a lower melting point than the base metal is used as filler metal.read more
MIG welding of aluminium can be performed in the short, spray or pulsed arc. The advantages of the pulsed technique are that spatter formation is reduced and a wire electrode with the next largest diameter can be used. The larger diameter wire is easier to feed and,...read more
