Iron and steel are easy to oxidize in high temperature. Aluminizing diffusion is a reliable surface treatment process. Spraying aluminizing is one of them.It has the advantages of wide range of application, relatively simple process and good high temperature resistance. The melting point of aluminum is 660 degree centigrade, and itself is not resistant to […]

For pure aluminum pipeline of concentrated nitric acid (> 99.8%) cooler. Advanceing welding equipment and reasonable welding process are needed to meet the production requirements.Because the characteristics of the material and the particularity of the welding process Aluminum and aluminum alloy materials are widely use in modern industrial production. In the chemical industry, it is a […]

Regulations for welding process approval in shipbuilding In the process of shipbuilding, welding process evaluation test is usually carried out for the determined base material and welding materials.  After certain technological welding, the applicability of the process is evaluated by checking the properties of welding seam and heat-affected zone. As welding process evaluation is great significance […]

Welding Technique The above figure mainly illustrates the welding technology and distribution of structural materials use in automobiles.  Mainly involving the welding of high-strength steel; aluminum and composite materials;  and the welding of dissimilar materials between them. Basically summarized the automobile related welding technology. According to the technology maturity, it can be divided into three layers: […]

2019-08-20 In the previous article we discussed 4043 and 5356 filler metals. It is a fact that these two filler alloys represent 80 percent of the worldwide consumption of aluminum filler metals. So it stands to reason that you should be using one of these filler metals for roughly 80 percent of your applications. But what […]

A  customer said that I fabricate high-end, custom, aluminum-framed bicycles. I was able to buy round tube made from alloy 7075 in the correct sizes to make bicycle frames. I checked the mechanical properties and found out that the strength of this alloy is very high. However, I have been unable to find the correct filler […]

Customer enquiryabout ER 4043 andER4047 A customer who often use ER4043aluminum welding wire for welding 6061 and casting asked us: someone suggested to him that ER4047 should be used as filling welding material, because it has better welding effect.But we know that ER4047 is more expensive than ER4043. Is it necessary to adjust under this […]

Copper and aluminum brazing method introduction Thoroughly remove the oil stains, dirt, insulation layer, etc. on the base metal before welding; Firstly heat the base material during welding,  heat thethinparts after the thick parts; heat the aluminum parts after the copper parts. Moving the welding gun back and forth evenly to heat the welding when […]

With the increasing environmental pollution problems, the energy-saving and consumption-reducing effects brought by automobile lightweighting , and it have become more and more popular.   automotive lightweighting: http://www.focusweld.com/?p=3134&preview=true In the field of automotive lightweighting, the application of aluminum alloys is increasingly widespread, especially for aluminum alloy profiles. Due to the short development cycle, The cost […]
