Introduction to Welding Methods for Portal Cranes

For large lifting equipment such as gantry cranes, the success of welding mainly depends on correct guidance. Let's determine how the gantry crane is welded. There are many aspects that need to be observed. The welding process factors that affect the tensile strength and bending performance of welded joints include welding method, type of base material, number of welding electrodes, type of shielding gas, etc. If these factors change, the entire gantry crane will have to re evaluate the welding process.

Do not underestimate some secondary factors, re evaluate them without changing them, and say that secondary factors are not important. If you encounter a welding seam on a crane that is operated by two or more welding methods, it should be evaluated for each welding process or welding process. Of course, combination evaluation is also possible.

Therefore, for the welding standards of gantry cranes, there are correct specifications and guidance to avoid detours, so that the functions of gantry cranes can be fully utilized without affecting the use of equipment.
