How hot does a welding arc get
WebHeat at a high temperature causes a weld pool of molten material which cools to form the join, which can be stronger than the parent metal. Pressure can also be used to produce a weld, either alongside the heat or by itself. It can also use a shielding gas to protect the melted and filler metals from becoming contaminated or oxidised. WebThe arc welding process requires a live electrical circuit. This means all arc welders using hand-held equipment are at risk of electric shock and electrical burns. The risk for MIG/ MAG and TIG welding is much less, as the welding current is normally switched on and off using the trigger or foot switch. For all arc welding, make sure:
