What kind of welding rod is good for welding machine parts?
First look at the material, some materials weldability, and some bad, and some to be welded in a particular environmentMechanical parts are mainly carbon steel, copper and aluminum.Carbon steel according to the accuracy and requirements, can be hand welding, CO2 welding, argon arc welding, arc welding, and so on. Weldability is good, medium carbon steel and high carbon steel weldability is generally or even bad.General general 10: carbon steel, low alloy steel electrodes, molybdenum and chromium molybdenum steel electrodes, low temperature steel electrode, stainless steel electrode, welding electrodes, cast iron electrode, nickel and nickel alloy electrode, copper and copper alloy rods, aluminum and Aluminum Alloy electrode and special electrode
Ordinary material steel use 502 of it
See the fittings material, low carbon steel welding good, any welding rod can. Medium carbon steel with good crack resistance of low hydrogen type electrode (such as J426, J427, etc.), welding seam has equal strength requirements, is to choose the intensity level of the electrode. As for other alloy materials, welding should pay more attention to it
