Automatic electric control pressure welding method

Abstract

The invention discloses an automatic electric control pressure welding method. The automatic electric control pressure welding method comprises the following steps: (S1) material preparation: workpieces needing to be welded are prepared; the quality of welded workpieces is checked; and the welded workpieces are qualified to enter a next procedure; (S2) equipment inspection: an air pressure weldingmachine is detected if the operation is normal; and when the operation is normal, the air pressure welding machine can enter a next procedure; (S3) welding preparation: the workpieces needing to be welded in the step (S1) are put on the air pressure welding machine, and are fixed by using fixtures; and the firmness of the fixation is checked after fixation; and (S4) welding: after the workpiecesare fixed, the positions, needing to be welded, of the workpieces are heated; and after the heating is finished, an electric control press applies pressure to the workpieces for welding. The appearance inspection and the compactness inspection are performed on the welded positions, so that the existing problems can be timely discovered, the defects are eliminated, and the welding quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to an automatic electric control pressure welding method. Background technique [0002] Welding, also known as welding or welding, is a manufacturing process and technology for joining metal or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. Welding achieves the purpose of joining through the following three ways: 1. Fusion welding - heating the workpiece to be joined to make it partially melt to form a molten pool, and the molten pool is cooled and solidified before joining. If necessary, fillers can be added to assist. It is suitable The welding process of various metals and alloys does not require pressure; 2. Pressure welding - the welding process must exert pressure on the weldment, which belongs to the processing of various metal materials and some metal materials; 3. Brazing - using a base metal The metal material with l...

Welding achieves the purpose of joining through the following three ways: 1. Fusion welding - heating the workpiece to be joined to make it partially melt to form a molten pool, and the molten pool is cooled and solidified before joining. If necessary, fillers can be added to assist. It is suitable The welding process of various metals and alloys does not require pressure; 2. Pressure welding - the welding process must exert pressure on the weldment, which belongs to the processing of various metal materials and some metal materials; 3. Brazing - using a base metal The metal material with low melting point is used as solder, and the liquid solder is used to wet the base metal, fill the joint gap, and interdiffused with the base metal to realize the joint weldment. It is suitable for welding processing of various materials, and is also suitable for different metals or heterogeneous materials. There are many kinds of energy sources for modern welding, including gas flame, electric arc, laser, electron beam, friction and ultrasonic, etc. In addition to being used in factories, welding can also be carried out in a variety of environments, such as field, water No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken when welding. Possible injuries caused by welding to the human body include burns, electric shock, visual impairment, inhalation of toxic gases, Excessive ultraviolet radiation, etc. With the advancement of science and technology, automatic welding has replaced traditional manual welding, but the existing automatic welding technology is not convenient to inspect the welding position after welding, and the welding quality cannot be guaranteed
