P309
DESCRIPTION
The P309 is a rutile coated stick electrode depositing an austenitic-ferritic 24 % Cr-13% Ni weld metal with a ferrite content of approx 15%, thus ensuring good resistance to cracking.
APPLICATIONS
The P309 electrode was designed to weld Type 309 stainless steel. It has excellent corrosion resistance at normal temperature and has outstanding oxidation resistance as well as high strength. It is recommended for joining dissimilar metals such as 18-8 stainless steel to mild steel and “hard to weld” hardenable steels.
Specifications P312
DESCRIPTION
A titanium type coated stick electrode depositing an austenitic-ferritic 29% Cr-9% Ni weld metal with a ferrite content of 25-30% thus ensuring high resistance to hot and cold cracking. It is ideally suited for maintenance and repair welding.
APPLICATIONS
The P312 electrodes are used in the jet aircraft industry. They are also used to weld dissimilar metal compositions, of which one component is high in nickel. The P312 is a special electrode for difficult-to-weld steels and for welding stainless steel to unalloyed steel.
P1001
DESCRIPTION
Coated electrode for gouging and grooving metals and alloys, including mild steels, stainless steels, cast iron, nickel, copper, and copper alloys. A highly efficiency electrode that performs with all types of welding machines.
APPLICATIONS
Hold electrode at a low angle close to the work piece (approx. 20°C). Point the electrode in the direction of the desired groove, strike the arc and push the electrode, maintaining as short an arc as possible so that the melted metal doesn’t drip onto the welded piece- For deep grooves use multiple passes. For hole cutting, strike the arc with electrode at right angle to work piece and pump up and down until work is pierced.
