Lec 19 – Resistance welding processes: spot and seam welding

Hello I welcome you all in the second lecture on the Resistance Welding processes In the last lecture I talked about the basic principles by which heat by which weld joints are developed And we know that in the distance welding processes the heat used for the development of joint comes from the I square […]

How to Make The Metal Melter

In a previous video I used a modified Microwave Oven Transformer as an electrical metal melter. In this video you’ll learn step by step how it was made, and what I’m using it for now. In a previous project, I found an old microwave in a dumpster and hacked it open to see what components […]

Mod-01 Lec-30 Gas Metal Arc Welding-II

The conditions are such that, means you have the electrode DCEP means, direct current electrode positive. You have a relatively lower level of current and then, irrespective of the type of shielding gas, we have globular transfer. So, the molten drop grows in size with the increasing current from its lowest value, when the arc […]

Make a Spot Welder for Cheap!!

A typical resistance spot welder like this can range in price from around $200 to over $800! That’s a little out of my price range, so for this project let’s make this one from common materials, and for just a few bucks! This modified transformer is the heart of the Spot Welder, and you might […]
