Welding Products for Joining AR400, TriBraze®, Manganese, or other wear resistant steels to themselves, each other or mild steel.

Use this chart to select the best choice for your application.

The welding products are listed in numerical order, with the product description:

Tri-Weld 3 - The correct stick electrode for joining Tri-Braze, AR400, AR500 and most any abrasion resistant plate, including manganese. Containing the correct amount of nickel, it is very crack resistant in these products, while maintaining good strength, flexibility and excellent toughness. An all position electrode with a low hydrogen type flux coating. It can also be used for buildup. We have used it to build up hammers and other worn areas. Polarity is AC or DC electrode positive.

Tri-Weld 3-FCG - This is the flux cored wire version of Tri-Weld 3. It has all of the same properties as the stick electrode and is an all position wire. Gas is required and it does form a light flux that must be removed between passes. Straight C02 or 75% Argon 25% C02 may be used. It can be used in all of the same applications as the stick version. It is a very smooth running wire and is very popular in the accounts that use it. Mild steel may also be welded with it but it is a slight overkill. Polarity is DC electrode positive.

Cast 25 - This is a premium stick electrode for the repair of cast iron as well as joining cast to steel. It is an all position alloy, with a nice looking, machinable, weld deposit. To repair a crack, you should gouge or grind a groove into the crack preferably the full depth. The area to be welded is to be free of grease, rust, paint, etc.  A slight preheat to 150 - 200 degrees will help remove moisture and oil or grease. Welds should be applied in short stringer beads, not exceeding 2" long.  Polarity is DC electrode positive.

Multi Alloy 85 - This is a stick electrode that is a versatile, very high strength stainless type alloy used for many applications including joining steels when you are unsure of the type or grade. It is used as a buffer between the joining weld and hardsurface when fabricating Super C to prevent check cracks from working into the weld. Build up of worn areas before hardsurfacing is another application. Multi Alloy 85 is also used for removing broken studs. It is NOT a very good all position electrode; however an experienced welder can manage the small diameters acceptably. The welds are very flexible and forgiving to cracking. Polarity is AC or DC electrode positive.

Multi Alloy 95 - This is a special stainless steel electrode designed to run in a vertical down position. It has a high tensile strength (105,000 PSI) and will help an inexperienced welder deliver quality welds. One of the most common uses is patching cracks or leaks in hard to reach areas until proper repairs can be made. It has a fast freezing flux designed to prevent slag entrapment in the down hand position. Uses are not limited to stainless. It can be used on other steels. This is a great maintenance welding alloy.  We stock this in 3/32 diameter. Polarity is AC or DC electrode positive.

Prime Arc 100 - The Weld Eraser - this rod welds nothing!  These electrodes are designed for gouging and metal removal when carbon arc gouging is not available or just a quick fix is needed. They run at relatively high amperage and have a specially designed flux to push the molten metal out of the way as you "jab" the rod at the crack. NOTE: THESE RODS RUN DC ELECTRODE NEGATIVE, or STRAIGHT POLARITY. This allows the electrical current to work with the special flux to actually remove metal rather than deposit it. When used correctly, these rods actually do a much cleaner job than you might expect. They can be used to gouge a groove or actually make a cut. For the best results, you should only try to go as deep as about 75% of the diameter of the rod in each pass. They may also be run in AC current but the DC straight polarity works best. Recommended amperage: 1/8, 200 - 300 amps, 5/32, 300 - 400 amps and 3/16 350 - 475 amps. 
 
Multi Alloy 238 - This is a mild steel electrode designed to weld through basically any of the problems encountered in repairs; (oil, grease, paint, galvanizing, dirt and slag) and still be very easy to use. It is a very good choice for maintenance people who are not accomplished welders. Virtually anyone can run it in all positions with very little practice. It will weld through its own slag without chipping between passes. Tensile strength will run about 75,000 - 80,000 PSI. Current can be AC or DC electrode positive or negative. We stock this in 3/32 and 1/8 diameters.

Multi Alloy 275 - This is basically the high strength version of Multi Alloy 238. It works very well running through the trash and dirt, but it not quite as easy to run. It is not difficult at all, but it will run more like a basic low hydrogen electrode such as 7018. Tensile strength runs around 115,000 PSI with about 23% elongation. The primary steels this would be used on would be T-1, HY 80 and other high tensile products. This rod runs very smooth and the slag removal is easy. It should be run DC electrode positive but it can run on AC current also. We stock this in 1/8, 5/32 and 3/16 diameters.

Multi Alloy 275-FCG- This is a high strength, flux cored gas shielded wire. It is comparable to the 275 rod in strength and elongation but it does not have the ability to weld through the trash. Small diameter wires do not have enough room to put the heavy fluxing agents inside that would be required for that. Low temperature toughness and crack resistance is very good on this electrode also. This wire runs very smooth and spatter free and is good for all positions. We stock this in .045 and 1/16 diameters. Gas shielding would be 75% argon 25% C02 or straight C02. It should be run DC electrode positive.

Multi Alloy 276-FCO - This is a high strength open arc wire designed for use on low carbon and low alloy steels. It can also be run in all positions. Although it is high strength, (100,000 PSI) it is not recommended for low temperature applications. When using this wire on material ~. and above, you should preheat to 300 F minimum. The maximum thickness to be joined with this product would be W. It has a very smooth arc and produces low spatter. Applications would include maintenance welding and structural fabrication. It should be run DC electrode positive. We stock this in 1/16 diameter but it is available in .045.

Multi Alloy 855-FCG- This is the flux cored wire version of Multi Alloy 85. It will do everything the rod will do except stud removal, yet still retains the same strength and flexibility. The wire, IS ALL POSITION, however, GAS IS REQUIRED and 75% Argon/25% C02 or straight C02 may be used. It does form a light flux that must be removed between passes. This is another very smooth running product that is popular with welders. Polarity is DC electrode positive.
