DIN 1732                          EL- AI 99.5

No. of Material                        3.0259

AWS/ ASME SFA - 5.3           E 1100

 

Application / Properties: Electrode with special covering for the welding of aluminum silicon alloys and for joining dissimilar aluminum alloys. The electrode should be held perpendicularly to the workpiece and a short arc length maintained. Plates thicker than 10 mm and larger workpieces require preheating in the range of 150 to 250 C. Since slag residues arc corrosive, the must be completely removed from the welded bead. Electrode serves well as consumable in oxyacetylene welding. The covering being hygroscopic, the electrode must be stored in an absolutely dry location, or redried if required.
