A 4.1kg packet of 3.2mm E309MoL-17 P5 4D (VDX) AC/DC highly alloyed, low carbon covered electrodes from Avesta. Can weld in the vertical down position.

Characteristics:
AVESTA P5-4D is a molybdenum-alloyed electrode of the 309LMo type, which is primarily designed for surfacing low-alloy steels and for joining stainless and low-alloy steels (dissimilar joints). When used for surfacing, the composition obtained is more or less equal to that of ASTM 316 from the very first run. AVESTA P5-4D is primarily intended for pipe and position welding, but can also be used as a general purpose electrode, especially for thin material.

Pipe welding can be performed in several different ways. One possibility is to start welding in the overhead position (1), followed by verticaldown on both sides from the 12 o’clock position (2 and 3). Another possibility is to start at the 7 o’clock position and weld vertical-up to the 11 o’clock position on both sides. This requires an inverter power source with a remote control.

DC– is often preferred to bridge large root gaps and when welding stainless to unalloyed thin plates and pipes.

Interpass temperature: Max. 150°C.

Heat input: Max. 2.0 kJ/mm.

Heat treatment: Generally none. For constructions that include low-alloyed steels in mixed joints, a stress-relieving may be advisable. However, this type of alloy may be susceptible to embrittlement-inducing precipitation in the temperature range 550 – 950°C). Always consult the supplier of the parent metal or seek other expert advice to ensure that the correct heat treatment process is carried out.

Structure: Austenite with 15 – 20% ferrite.

Scaling temperature: Approx. 950°C (air).

Corrosion resistance: Superior to 316L. The corrosion resistance obtained in the first layer when surface welding corresponds to that of 316.
