Two different modes of laser welding
2020-03-18 639
When using a laser welding machine for laser welding, there are two different ways or the energy can be transferred from the laser to the welding data. Depending on the power density, which is the power factor of the laser and the weld area, the laser welding method can be in the form of conduction or keyhole. You may be familiar with it now because it is a form of keyhole that is often used in craft welding. It should be emphasized that the type of welding that is occurring is determined by th

How to clean the welding roller frame?
2020-03-11 567
Welding roller frame is often used in our industrial production, but it is also easy to get dirty, especially the bottom of the frame, which is difficult to clean. The following intelligent product series will show you how to clean the bottom of the drum structure, clean the bottom of the drum structure? The cleaning of roller frame needs special cleaning agent. Before cleaning, remove the other disassembled parts of support wheel and tube wheel; put the disassembled parts into the container, a

Preparation for welding stainless steel pipe
2020-03-05 562
No matter what product must have certain preparation and inspection, so before welding stainless steel pipe. Targeted preparations should be made. This preparation is an important part to ensure the welding quality. The content is mainly considered from the following three aspects: the recognition of the skills of stainless steel welded pipe welding operators. It is necessary for welders engaged in welding operations to work with certificates and strictly follow the allowable welding items ind

The thickness of workpiece should be set when using welding equipment
2020-02-21 567
Before using manual flume welding equipment, it is necessary to check the voltage and current. In order to ensure that it is within the rated power range of the machine, it should not be too high or too low. However, only under normal conditions, welding will definitely affect. As long as ability is used, it can guarantee the function. Also pay attention to the parameter setting of welding machine, which needs to be set according to different workpiece and different thickness. In particular, th

Function of silicon controlled rectifier in resistance welding machine
2020-02-14 691
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
2020-01-14 518
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
2019-12-20 533
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?
2019-12-20 548
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

Methods to reduce welding deformation and control
2019-12-20 579
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
