About Dongbo

I am an experienced Plumber and Welder with over 21 years of expertise in the construction, renovation, and manufacturing industries.
Core Technical Skills: I specialize in advanced welding techniques, including GTAW (TIG) for stainless steel and SMAW (Stick) for iron piping.
Technical Breakthroughs: I have extensive experience in solving complex technical challenges, particularly in the specialized welding of dissimilar metals, such as joining stainless steel to copper, copper to aluminum, and stainless steel to aluminum.
Project Experience: My expertise includes medical gas piping, biological laboratories, ultra-pure water pipelines, and complex plumbing for kitchens, bathrooms, and HVAC systems (e.g., ground source heat pumps). I am also highly skilled in the fabrication and installation of wrought iron gates, stairs, and stainless steel handrails or guardrails.
Professionalism: Beyond technical execution, I am proficient in reading technical blueprints and possess strong practical skills and professional ethics. I look forward to applying my deep technical knowledge and problem-solving abilities to your projects.
