Welded parts and methods of manufacturing the same are disclosed. A welded part may include first and second metal workpieces (202, 204) having respective first and second edges forming a butt joint. The welded part may further include a first laser weld (208a) joining the first and second edges on one side of the first and second metal workpieces, and a second laser weld (208b) joining the first and second edges on another opposite side of the first and second metal workpieces. Some example parts may have laser welds that cooperate to extend across an entire depth of the butt joint and form an overlap zone (212) between the first and second laser welds. In some examples, the first and second laser welds may be formed with substantially zero macroporosity.
