How to weld titanium, Welders, please save this article
Titanium alloys have low density, high specific strength, good corrosion resistance, low thermal conductivity, non-toxic and non-magnetic, and can be welded; they are widely used in aviation, aerospace, chemical, petroleum, electricity, medical, construction, sports good...Read more -
Excessive force of arc welding droplets
01 Gravity of molten drop Any object will have a tendency to sag due to its own gravity. In flat welding, the gravity of the metal molten droplet promotes the transition of the molten droplet. However, in vertical welding and overhead welding, the gravity of the molten d...Read more -
Do you know these 8 tips to reduce splashing
When the flames fly, weld spatter on the workpiece is usually not far behind. Once spatter appears, it must be removed - which costs time and money. Prevention is better than cleanup, and we need to prevent weld spatter as much as possible - or...Read more -
Various welding methods
Hot air welding is also called hot air welding. Compressed air or inert gas (usually nitrogen) is heated to the required temperature through the heater in the welding gun and sprayed onto the plastic surface and the welding strip, so that the two are melted and combined ...Read more -

Xinfa welding equipment has the characteristics of high quality and low price. For details, please visit: Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com) 4. Arc pits It is a downward sliding phenomenon at the end...Read more -
Common quality problems of welding projects (1)
All defects that can be seen by the naked eye or a low-power magnifying glass and are located on the surface of the weld, such as undercut (undercut), weld nodules, arc pits, surface pores, slag inclusions, surface cracks, unreasonable weld position, etc. are called exte...Read more -
Aluminum alloy welding problems and methods
1. Oxide film: Aluminum is very easy to oxidize in the air and during welding. The resulting aluminum oxide (Al2O3) has a high melting point, is very stable, and is difficult to remove. It hinders the melting and fusion of the parent material. The oxide film has a high s...Read more -
What welders must know Macroscopic analysis of weld defects
The quality requirements for welded structures, welded products, and welded joints are multi-faceted. They include internal requirements such as joint performance and organization. At the same time, there must be no defects in appearance, shape, size accuracy, weld seam formation, surface and int...Read more -
What points should we pay attention to when welding high carbon steel
High carbon steel refers to carbon steel with w(C) higher than 0.6%. It has a greater tendency to harden than medium carbon steel and form high carbon martensite, which is more sensitive to the formation of cold cracks. At the same time, the martensite structure formed in the welding heat-affecte...Read more -
Welders, how do you understand steady, accurate and ruthless
After looking at the pictures above, do they look very artistic and comfortable? Do you also want to learn such welding technology? Now the editor has summarized his own methods for everyone to learn and communicate. Please feel free to correct me if I am wrong. It can be summed up in thr...Read more -
What is the reason for poor weld formation
In addition to process factors, other welding process factors, such as groove size and gap size, inclination angle of the electrode and workpiece, and spatial position of the joint, can also affect the weld formation and weld size. Xinfa welding equipment has the charact...Read more -
What is direct current connection, what is direct current reverse connection, and how to choose when welding
1. DC forward connection (i.e. forward connection method): The forward connection method refers to a wiring method used to measure the dielectric loss factor in the Xilin bridge circuit test. The dielectric loss factor measured by ...Read more
