For large lifting equipment, such as gantry cranes, the success of the welding depends mainly on the correct guidance. Let us judge how the gantry crane is welded. There are many aspects to be seen.
The welding process factors affecting the tensile strength and bending properties of the welded joint include the welding method, the type of base metal, the number of welding electrodes, the type of shielding gas, etc. If these factors change, the entire portal crane will have to re-evaluate the welding process.
Don't underestimate some secondary factors, do not change some secondary factors to re-evaluate, say that secondary factors are not important. If you encounter a weld on a crane that is operated by two or more welding methods, it should Evaluate each welding process or welding process. Of course, a combination evaluation is also possible.
Therefore, for the welding standard of gantry cranes, it is necessary to have correct specification guidance to avoid detours, so that the function of the gantry crane can play the maximum and maximum effect without affecting the use of the equipment.
