Hobart Brothers has developed its Hobart® Boilermaker™ family of low alloy stick electrodes. The family, which includes Boilermaker 18 (AWS E7018, E7018-1), Boilermaker 18A1 (E7018-A1), Boilermaker B2 (E8018-B2) and Boilermaker B3 (E9018-B3) stick electrodes, has been formulated to provide X-ray quality welds with no starting or stopping porosity. Hobart Brothers designed the Boilermaker stick electrodes to accommodate a wide variety of welding styles and also to provide several distinct characteristics. Low spatter levels and a removable slag both lessen downtime for post-weld cleaning and minimize the need for rework, while the products’ bead wash and arc starts and stops ensure good weld quality with no porosity. The Boilermaker stick electrodes burn evenly, especially when welding pick-ups on the tube sides. Because the Boilermaker stick electrodes operate at an amperage spread of 75 to 90 amps, they can be used to weld on both thin- and heavy walled boiler tubes without burn-through. Boilermaker B2 electrodes are available in 3/32in diameter 12in lengths. This 12in length allows welding operators to bend the electrode to fit in tight spaces common to boiler tube repairs and also allows for non-stop welding, again lessening the chance of starting and stopping porosity. All of the other Boilermaker products are available in 3/32in and 1/8in diameters in 14in industry standard lengths.
