Welding On Iron. The machining is required after we complete this process. The weld bead length and gap between depends on the required weld strength.
Welding cast iron is a battle against heat cracks. Cast irons are alloys of iron carbon and silicon may have over 2 carbon and 1-3 silicon and may include specific amounts of other elements to achieve definite characteristics. Normally when you are learning how to weld Cast Iron you would pre-heat the base metal to at.
Also move slowly in a stitch-like manner.
The 44- and 55-percent nickel-iron electrodes should be in conformance with class designation AWS A515. A low amperage is needed to avoid deep fusion between the base material and filler. Ad Find China Manufacturers Of Mig Welding. Ad Find China Manufacturers Of Mig Welding.
