How to maintain manual water tank welding equipment
2020-02-18 293
The following points should be paid attention to in the maintenance of welding roller carrier: 1. Check whether the external environment meets the requirements and there is no interference from sundries; 2. Operate in the air with electricity, without abnormal noise, sensation and smell; 3. Check whether the bolts at the mechanical connection are loose, and if they are loose, they can be used after fastening; 4. Check whether there are impurities on the guide rail of the assembly machine and the

Function of silicon controlled rectifier in resistance welding machine
2020-02-14 385
What is the function of SCR in resistance welding machine? It is widely used in automatic control, electromechanical field, industrial electrical and household appliances. Thyristor is an active switching element, which is usually kept in the non channel state until it is triggered or "lit" by less control signals. Once lit, it will hold the channel through even if the trigger signal is evacuated, and then it can be cut off by increasing a reverse voltage between its anode and cathode, perhaps

How to use automatic welding equipment in all position welding
2020-01-14 305
First, the active welding equipment is applied in omni-directional welding, and the rotating pair driving method is adopted for welding performing parts, which can flexibly and reasonably change the welding torch posture, which is conducive to the all-round welding operation. When the same welding parts are driven together, the motor power can also be reduced. In the application, the sensor of welding orientation is installed on the final reduction shaft, so as to detect the welding gun orientat

Daily maintenance of automatic welding machine
2019-12-20 308
There are many classification methods of welding, which can be divided into fusion welding, pressure welding and brazing according to their process characteristics: 1. Fusion welding is the abbreviation of fusion welding, which heats the joint part of two weldments to the melting state, participates in (or does not participate in) filler metal, and makes it cool and condense into a whole under no pressure, so as to complete the welding. Gas welding, shielded metal arc welding, submerged arc wel

What is the difference between domestic and foreign straight seam welding machines?
2019-12-20 303
There are many ways of longitudinal welding machine, so different welding power sources should be used according to different workpiece shape, size, raw material, thickness and welding forming requirements. According to the daily practice, this paper sums up the following points about the welding heat source of the longitudinal welding machine: plasma arc welding plasma arc welding is an inert gas maintenance arc welding, which uses the tight arc between the electrode and the workpiece for weld

Features of automatic welding machine for flume
2019-12-20 309
Water tank acid and alkali resistant, oxidation resistant, beautiful surface! Today, we will introduce the welding process of the sink! From the perspective of flume shopping malls, there are three kinds of integral stamping (also known as overall stretching or conjoined stretching), roll welding (also known as bottom welding) and butt welding. Both of them belong to the welding basin. Most of the products are produced by roll welding process, which is mainly to stretch two single groove tanks,

Methods to reduce welding deformation and control
2019-12-20 335
I. causes and types of welding deformation causes of welding deformation: welding deformation refers to the deformation of weldments during and after welding. During welding, the molten metal and the base metal near the seam expand and produce plastic deformation. During solidification, the weld and the metal near the seam contract. This is the longitudinal stress and the transverse stress. Make the weld longitudinal and transverse shrinkage, so that the weldment deformation. Because the heat e

Specific differences between grinding machine and polishing machine
2019-12-20 344
Difference: the workpiece processed by grinding machine is rough, and the surface finish of workpiece processed by polishing machine is better, but high finish can be achieved by installing precise grinding wheel on grinding machine. Grinding machine: electric grinder reciprocating electric polishing grinder (also known as file mill). It is widely used in the fine machining and surface polishing of the mold profession. It is a substitute for similar pneumatic products. The main outstanding featu
