At ELLWOOD Crankshaft Group, we're dedicated to delivering top-notch counterweight solutions to our customers. Our counterweight assemblies undergo a meticulous pre-heat process to guarantee consistent and high-quality weld performance. We utilize a GMAW (Gas Metal Arc Welding) process approved by major Marine Classification Societies, along with certified welding consumables, to weld the counterweights to the crankshaft. Prior to post-weld heat treatment, all weld-on counterweights undergo a magnetic particle inspection to ensure that no external defects are present. We also apply a full mechanical post-weld heat treatment to minimize the effects of heat-affected zones commonly found in GMAW welding processes. Additionally, our expert welders are qualified and certified per AWS structural welding code, D1.1. Should the need arise, we have the capability to perform submerged arc welding to restore running surfaces on diameters requiring repair or refurbishment.
