Abstract

The invention discloses a solder welding method, which comprises the following steps: step 1: preparing tin, a solvent, a terminal plate and a base frame; step 2: skimming the terminal block and hanging the tin; step 3: skimming the bottom frame joint and melting tin at the joint; step 4: terminal block and bottom frame solder welding; step 5: washing the solvent attached to the terminal block andbottom frame by hot water. Compared with the prior art, the solder welding method effectively solves the welding of stainless steel and copper plate, and the products after welding are beautiful andfirm in appearance; the solder welding method has the advantages of simple process and high production efficiency.

Description

technical field [0001] The invention relates to a welding method, in particular to a soldering method. Background technique [0002] For soldering, metals such as alloys, gold, silver, zinc, and nickel have good solderability, while metals such as aluminum, stainless steel, and cast iron are poorly solderable. The terminal board on the pantograph and the bottom frame are fused together by stainless steel and copper plate. The traditional soldering method is adopted. The welding is uneven, the solidification is not good, the bottom frame is easy to fall, and the appearance is not beautiful. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a soldering method for the above-mentioned deficiencies in the prior art. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A soldering method, comprising the steps of: [0006] Step...
