HVAC Welding | Weld Quality
Welding is a primary area of GEA expertise which includes all facets of the science, art, and application of a broad range of metal joining processes. GEA combined welding experience exceeds 100 years including process expertise in:
- Resistance (Spot) Welding
Some will (incorrectly) include other metal joining and metal cutting methods such as:
- Brazing (See our HVAC Brazing services)
- Manual Oxy-fuel
- Plasma cutting
Though technically these are not welding (see definitions in left column) our expertise does include these processes also.
Applicable products include:
- shell and tube heat exchangers
- fin and tube heat exchangers
- building structures
- sheet metal products.
Arc Welding is used for the main chambers of heat exchangers and steel compressors. Main components are called shells, tube sheets, nozzles, couplings and piping (usually 3 inch diameter and larger).
GEA Weld Experts Can Help With:
- Conformance to codes, standards and specifications. Examples are ASME, AWS, European PED, ISO and OSHA for safety.
- Development of Quality Assurance Manuals for the Customer’s business needs. This includes all weld process control requirements.
- Determination of true requirements of product to be weld fabricated including Design for Manufacturing.
- Process training and qualifications.
- Auditing to insure continued effectiveness of training.
- Welding Equipment and Consumables - Evaluation, specification, runoff, safety, documentation, installation, maintenance, training, and auditing.
- Fixturing and tooling – Design, evaluation, specification, safety, runoff, documentation, installation, maintenance, training, and auditing.
- Material Handling – Specialized design for specific welded product or to cover a range of products.
- Development of repair procedures to correct base metal and filler metal nonconformities.
Weld Quality is Critical
Welding is synonymous with Quality. It is uncompromising. It is attention to detail; from material selection to fixturing, to welder training. Read Bill Spietz blog post listing the Key Variables and Hidden Variables that need be controlled.
