Yes, we have several full-time engineers ready to assist customers with technical support problems, feeder or welder integration difficulties or control issues that may arise during the quoting or installation process, as well as after market support.

The purpose of a welding curtain or screen is to protect passers by and nearby workers from the welding arc light. Where welding takes place and other people are likely to be close-by, there should be something in place to prevent them being affected by the light. In practice this protection is often achieved by using curtains or screens.

There are many other forms of welding which do not use a welding torch to connect materials. Ultrasonic welding uses high frequency vibration to connect thin metal sheets or plastics. There is also roll welding where two pieces are run through two high pressure rollers to clamp them together. Electricity can be used to weld metals but applications are a bit limited because the cost can be high.

Many types of metals out there can be welded to create a strong bond but there are exceptions to this rule. For example, aluminum and steel cannot be welded together because they have different melting points. As steel takes roughly twice the temperature of aluminum to weld, the aluminum becomes a liquid and will not stay near the steel. But beyond this, when aluminum and steel fuse together they form a brittle bond that is not very effective.

The answer is both yes and no. Traditional welding is done by heating up two pieces of metal that become molten along an edge and are fused together. Soldering involves not heating up the two pieces of metal but melting a lower melting-point material between them to cause a joint. So, soldering is a form of welding as welding involves heat and connecting two different components but it is not strictly welding as it uses an intermediary to create a joint.
