Welding temperature control method

Abstract

The invention provides a welding temperature control method, The method comprises an automatic welding equipment, wherein the automatic welding equipment comprises a welding gun, a temperature controlsystem and an identification system, the identification system is used for identifying identification information of a piece to be welded, the temperature control system is used for calling out corresponding welding process parameters according to the identification information, the gas flow of the welding gun is automatically set based on the welding process parameters, the welding process parameter comprises the target temperature of a welding seam, pipe diameter, wall thickness and other automatically set welding parameters; and the temperature control system comprises a temperature monitoring head, wherein the temperature monitoring head is used for monitoring the real-time temperature of the weld seam, and when the difference value between the real-time temperature and the target temperature exceeds a first threshold value, the temperature control system adjusts the gas flow of the welding gun, so that the difference value between the real-time temperature and the target temperature is smaller than the first threshold value. The welding parameters are automatically called out through identification information, automatic implementation is facilitated, human errors are avoided, automatic shutdown caused by temperature abnormity is avoided, and lot-size problems are eradicated.

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.

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.
