Description
Technical Field
The utility model belongs to the technical field of the welding equipment technique and specifically relates to a but quick assembly disassembly contact tube.
Background
In the submerged arc welding process, the flux-cored wire is continuously input into a molten pool and is melted under the high-temperature action of an electric arc formed by the positive electrode and the negative electrode, and finally a welding seam is formed. The contact tip is used as the anode, and the welding wire continuously rubs the inner hole in the welding wire input process and is influenced by high temperature, so that the size deviation of the inner hole is very easy to cause, and the welding seam quality is influenced. In order to ensure the quality of welding seams, the contact tip needs to be frequently replaced; under the condition that a plurality of machine heads are welded simultaneously, the frequency of replacing the contact tube is multiplied; if equipment breaks down or open arc occurs in the welding process, the contact nozzle is worn quickly. Through statistics, the average service life of the contact tube is 24 hours, the contact tube is influenced by the structure of the contact tube, 7-8 minutes are needed for replacing one contact tube, the contact tube is frequently replaced, the required time is long, the production efficiency is influenced, and the workload of workers is increased.
