What are the Best technique for overhead and vertical up welding?

The best technique for both is a "whip" or "step" motion. This is where, say we are doing a vertical weld, we would strike the rod at the bottom and proceed to move up going about a half inch up and then a quarter inch back, half inch up and quarter inch back. Keep doing this until you've either finished your weld or your stick is no longer usable. Same with the overhead, using a "step" technique gives you more control. The only thing you will need to do is practice, practice, practice.

What is spot welding?

Spot Welding is a process where two pieces of overlapping metal are welded by applying an electric current through two contact points. The interface of the parts creates current resistance which produces heat. The two metals form a "button" type weld when pressure is applied. The welds will be of the approximate size of the contact points and the filler metal consists of the base materials only (additional material is not generally added). The equipment used for spot welding in smaller operations would consist of a set of "tongs" that apply current and pressure to the parts being welded. This process can be accomplished using a portable unit or an automated process such as with automobile manufacturing.Workpieces are held together under weight applied by anodes. Normally the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness extend. The procedure utilizes two molded copper combination anodes to gather welding current into a little "spot" and to at the same time cinch the sheets together. Driving a vast current through the spot will dissolve the metal and shape the weld. The appealing element of spot welding is that a considerable measure of vitality can be conveyed to the spot in a brief span (roughly 10-100 milliseconds).[2] That allows the welding to happen without over the top warming of the rest of the sheet.The measure of warmth (vitality) conveyed to the spot is controlled by the resistance between the terminals and the size and length of the current.[3] The measure of vitality is coordinated the sheet's material properties, its thickness, and kind of cathodes. Applying too little vitality won't dissolve the metal or will make a poor weld. Applying a lot of vitality will soften an excessive amount of metal, launch liquid material, and make a gap as opposed to a weld.[4] Another element of spot welding is that the vitality conveyed to the spot can be controlled to deliver solid welds.Projection welding is an alteration of spot welding. In this procedure, the weld is limited by a method for raised segments, or projections, on either of the workpieces to be joined. Warmth is amassed at the projections, which allows the welding of heavier segments or the nearer dividing of welds. The projections can likewise serve as a method for situating the workpieces. Projection welding is regularly used to weld studs, nuts, and other screw machine parts to the metal plate. It is additionally oftentimes used to join crossed wires and bars. This is another high-generation prepare, and numerous projection welds can be masterminded by reasonable outlining and jigging
