When to Weld and When to Fabricate New: A Guide for Hydraulic Equipment Repairs

https://readharvesty.com/s/YTF4h9WxYldL1hm8slF79

Whether to weld or fabricate new parts for hydraulic repairs depends on weld quality, safety, and economics. Welding is ideal for non-structural cracks and minor leaks on thick-walled components using proper preheat and filler. Fabrication becomes necessary when fatigue cracks or corrosion compromise the parent metal's strength, pitting is deeper than 10 percent of thickness, or the component has been repaired before. Complex geometries, high-pressure lines, and attachment points often warrant…
