NICORE 55伊萨焊丝.铸铁焊丝

Nicore 55 is a composite metal cored wire for repair and joining of cast iron materials. The deposit, which is approximately 53% iron and 45% nickel, provides an excellent match for the coefficient of expansion exhibited by cast ir***. Cracking is minimized because thermal stresses caused by the heat of welding are minimized. The light slag is easily removed enhancing visual weld inspection. The fact that this is a continuous electrode will improve the operating factor and minimize unnecessary stops and starts. This electrode can replace covered electrodes such as AWS ENiFe-Cl or ENiFe-Cl-A. It may be used for repair welds or for joining various types of cast ir***. Cast ir*** may be welded to steel and other ferrous and non-ferrous materials with this product. The machinability of the weld deposit is comparable to the matching covered electrode. Substantial s***ings in weld metal deposition costs will be realized when replacing 55% nickel coated electrodes with Nicore 55. The deposition rate of this wire is more than twice that of a comparable coated electrode. The efficiency (approximately 97%) compared to that of coated electrodes (56% assuming 3” stub loss) is substantially greater. These two factors result in substantial s***ings in weld metal deposition costs. Because of the high deposition rate, the tr***el rate is very fast, resulting in lower heat input which is advantageous in welding cast ir***.
