33 Electrode

Versatility

33 can be used for the repair of virtually any type or grade of stainless steel. This superior degree of versatility makes 33 the repair alloy to carry and stock in plants that use stainless equipment, such as food and beverage plants and chemicals processing factories.

33 is also a must in hotels and any kind of eating establishment because this advanced alloy repairs all grades of stainless, from utensils to counter tops, sinks, cookware and freezer doors and cabinets.

Improved Corrosion Resistance

33 features superior resistance to corrosion over ordinary stainless welding alloys due to special alloying elements that improve the weldment's corrosion resistance to reducing media, such as urea. This particular feature makes 33 the repair alloy of choice in fertilizer plants and factories.

Easier to Use, Even at Low Amperage

In repair welding requiring vertical downhand applications, 33 has no equal. Other welding rods fail this ease-of-use test when welding vertical downhand as the slag runs ahead of the weld.

33's special "controlled slag" action enables even inexperienced welders to make perfect vertical downhand welds on viturally any stainless steel repair. In addition, after welding, the slag blanket is easily removed.

Its superior AC weldability allows 33 to be applied "on site" or in difficult access situation as even small, portable AC open circuit welding machines will give good results, using low amperage.

This good weldability at low amperage also helps minimize burn-through, collapse or stainless discoloration, when welding on thinner stainless pieces.

Mechanical Properties

Tensile Strength: 86,000 psi
Yield Strength: 51,000 psi
Elongation: 35%
Impact (ISO-V): 52 ft/lbs

Application Procedure

33 can be applied using either AC current or DC reverse polarity. Steel surfaces to be welded should be degreased, but no other speical preparation is required, nor is preheating.

Tack weld the work piece every inch or so. It is not necessary to weave the weld but try to maintain a close arc. Peen each pass.

You will find the slag is easily removed and this should be done at the end of each pass. On vertical downhand applications, the arc transfer will remain even and no problems with the slag running ahead of the weld will be experienced.

33 will also weld perfectly "in situ" using even low amperage open-circuit welding machines, such as when repairs have to be made away from the workshop.

Recommended Amperage

3/32" 60 to 80 amps
