Molten metal slag can splatter several feet from a weld. Grinding sparks can fly even further. Any sawdust, paper or plastic bags in the area can smolder and catch fire, so keep a tidy area for welding.

Most often, your attention will be focused on the parts you are welding, and not the area around you, so it can be hard to see what's going on behind you if something catches fire. Reduce the chance of that happening by clearing away all flammable objects from your weld area. This is a good precaution for any shop, but keep a fire extinguisher beside the exit door from your workshop. CO 2 extinguishers are the best type of extinguisher for welding.

Water extinguishers are not a good idea in a welding shop since you are standing next to a machine which essentially transforms wall power into lightning.

The main types of welding used in industry and by home engineers are commonly referred to as MIG welding, TIG welding, arc welding, gas welding. Hands down, MIG welding is the most common form of welding practiced, but there are other options for fusing metal together.

The GMAW process is suitable for fusing mild steel, stainless steel as well as aluminum. MIG M etal I nert G as welding is a semi-automatic arc welding process in which a consumable wire electrode and a shielding gas are fed through a welding gun, also known as the torch. The machine produces massive electrical current that travels through the consumable wire to your work pieces fusing and melting both the wire and the base metal together.

MIG welding was developed in the 's as a way to speed up the way production welders fuse materials in factories during and after WW2. Seventy years later, the general principle is still very much the same but most MIG welding equipment has been modernized with better parts and some even have onboard computers.

MIG welding uses an arc of electricity to create a short circuit between a continuously fed positive anode the wire-fed welding gun and a negative cathode the base metal being welded. If you want a greater understanding of the core principles of electricity check out the Electronics Class. The heat produced by the short circuit, along with a non-reactive inert gas, melts the metals under the welding torch and allows them to mix together.

Once the heat is removed, the metal begins to cool and solidify, forming a new piece of fused metal. MIG welding is useful because you can use it to weld many different types of metals: carbon steel, stainless steel, aluminum, magnesium, copper, nickel, silicon bronze and other alloys.

This class only goes over how to fuse mild steel, but your welder's manual will have advanced instruction on how to weld other materials. Oxy-Acetylene Torch Welding , more commonly Gas Welding and Cutting , are not used as widely for general welding of mild steel, but great for very delicate assembly of small ornate parts.

This form of welding is one of the earliest industrial forms of welding. Gas welding consists of mixing oxygen and acetylene gas to create a flame capable of melting steels. The gas torch is commonly used for brazing softer metals such as copper and bronze, but can also be used for welding delicate aluminum parts such as refrigeration pipes. TIG welds are best suited for out high-touch work, such as sculptures and architectural features.

TIG welds provide a superior finish that needs minimal clean up by sanding or grinding. TIG welding provides a very clean way to weld. In one hand you wield a torch electrode and connect ground to your base material.

You activate the flow of current with a foot pedal and control the amount of current on the welder. Instead of a consumable wire feed being burned from the torch, the person welding gently feeds filler material from a rod into the welding pool. Since you control the feed of material, slag splatter is minimal.

If you are interested in learning more about TIG welding, check out this Instructable. Welder making boilers for a ship, Combustion Engineering Co. Photograph by Alfred T. Arc welding works by clamping a current producing electrode onto a coated consumable stick of material. An electrical arc travels from the tip of the consumable electrode to the base material underneath. The distance between the electrode tip and base material controls the amount of heat being generated by the super hot electrical arc.

Arc welding is best suited for structural manufacturing, construction, and large-scale repairs. Arc welds get very very hot, and can burn out thin material easily, thinner materials are more suited to the MIG welding processes.

Before going further in this class, please note that the lessons in this course only go over one of the kinds of welding listed above, MIG welding. MIG welding is the most common form of welding, albeit the price tag associated with a MIG welder can be high, it is the most accessible of welding skills to learn.

More on that in our upcoming lessons. Any good fabricator knows that improper measurement when working on any project is not advised and will lead to poorly crafted finished work. Be sure to invest in a number of reliable measuring and marking devices. The most common measuring tools you will need in your metalworking arsenal are tape measures, metal rulers, calipers, metal T-squares, and a marking tool of some kind.

H 21 - 26 Subject to cracking from thermal shock. H 26 Rockwell range HRC 35 - H 21 - 26 steels similar to T2 steels. H 21 Carbon 0. H 26 Carbon 0.

Ensure base metals are clean avoid tool marks. Remove all sharp edges and tight corners in weld areas. Majority of tool steels will be weld repaired in the Hardened condition.

Discoloration glazing of steel while grinding indicates damage. Preheating before grinding or oxy cutting prevents damage. Pre heat prevents cracking, distortion stresses and shrinking. Annealed or hardened steels the steel must be pre heated. If base metal hardened yet not tempered anneal temper first.

Preheat hardened steels don't exceed temper temperature. Annealed steels, preheat at maximum pre heat recommendation. Hardened steels, pre heat, weld temper then grind finish. Coating surface with Borax prevents decarburization. High temper provides more toughness with less hardness.
