Anatomy of Willard welding head

As we all know, Weile welding head is mainly composed of copper, iron, tin, nickel, chromium and five metals, but what roles do they play respectively? Let's take a look: First of all, copper, as a heat conductor, is the primary component of Weile welding head. Accounting for about 85% of the data in welding head, copper has good thermal conductivity, which is conducive to rapid warming. Good welding head is made of red copper, but some manufacturers use brass to save money, thus reducing the thermal conductivity of welding head.

      Iron coating plays an anti-corrosion role, which is the decisive factor of the life of welding head. Some customers who don't know much about the business also ask me how your welding head is made of iron, not copper. This is copper plated with iron, dear. Good welding head iron plating layer has fine and dense crystal structure and good corrosion resistance. Such welding head has long service life and good tin plating effect. Manufacturers with poor iron plating technology mainly rely on the thickness of iron plating layer to control the service life of welding head. Usually, when the iron plating layer is thick, the temperature rises slowly in welding head, and when it is thin, it is useless.

 Tin is on the head, which is the place where tin sticks. Nickel plays the role of rust prevention for the iron plating layer, and is convenient for chromium plating at the back. Chromium does not stick to tin, which prevents tin from running on welding head's body when it is used. Generally, the chrome plating time in welding head is more than 5 minutes, and the chrome plating time in decoration is about 1 minute. Chromium can be silver plated, white or black chromium. Tin ran to the welding head because the chrome plating layer was too thin or not well plated, which did not prevent tin from climbing. Ok, after reading this article, do you have a clearer understanding of Willard welding head?
