A kind of welding temperature control method

Abstract

The invention provides a welding temperature control method, which includes automatic welding equipment, the automatic welding equipment includes a welding torch, a temperature control system and an identification system, the identification system identifies the identification information of the parts to be welded, and the temperature control system according to the The identification information calls out the corresponding welding process parameters, and automatically sets the gas flow of the welding torch based on the welding process parameters. The welding process parameters include the target temperature of the weld, and also automatically adjust the welding parameters such as pipe diameter and wall thickness. Parameters The temperature control system includes a temperature monitoring head for monitoring the real-time temperature of the weld, and when the difference between the real-time temperature and the target temperature exceeds a first threshold, the temperature control system adjusts the gas flow of the welding torch to Making the difference between the real-time temperature and the target temperature smaller than the first threshold. Automatically call out welding parameters through identification information, which is conducive to automation, avoids human errors, automatically stops when the temperature is abnormal, and eliminates batch problems.

Description

technical field [0001] The invention relates to the technical field of gas welding, in particular to a welding temperature control method. Background technique [0002] The two types of heat exchangers, condenser and evaporator, are the core components of the air conditioner, and their welding quality is directly related to the noise, stress, and life of the air conditioning system. The key parameter that affects the welding quality is the welding temperature: if the temperature is too high, it is easy to overheat, resulting in coarse grains in the pipeline, cracked refrigerant leakage and failure, and at the same time, it is easy to form welding lumps in the tube, resulting in noise complaints such as howling and liquid flow; If the welding temperature is too low, the welding will not penetrate and the joint will be poor, and the pressure difference of the pipeline will easily vibrate and crack, resulting in refrigerant leakage and failure.

AI Technical Summary

Problems solved by technology

The disadvantage is that when the inspection finds that the temperature is abnormal, it often causes problems in small batches or large batches. Not only the cost of repairing and scrapping is high, but also the consistency of welding quality is difficult to guarantee, which seriously affects product quality.
