For large lifting equipment, such as gantry crane, the success of welding mainly depends on the correct guidance. Let's judge how the gantry crane is welded. There are many aspects to be observed.
The welding process factors affecting the tensile strength and bending performance of welded joints include welding method, type of base metal, number of welding electrodes, type of shielding gas, etc. if these factors change, the whole gantry crane will have to re evaluate the welding process.
Don't underestimate some secondary factors and re evaluate them without changing some secondary factors. Say that secondary factors are not important. If you encounter that the weld on the crane is operated by two or more welding methods, it should be evaluated for each welding process or welding process. Of course, portfolio evaluation is also possible.
Therefore, for the welding standard of gantry crane, there must be correct specification and guidance to avoid detours, so that the function of gantry crane can play a great and great role and will not affect the use of equipment.
