Product Description

Specification

Discription

Our professional welding services cover a full range of industry-standard processes, including Shielded Metal Arc Welding (SMAW)—also known as stick welding—using flux-coated electrodes for unmatched versatility in on-site fabrication, repair, and outdoor jobs. We utilize Gas Metal Arc Welding (GMAW/MIG welding), which feeds a continuous solid wire electrode with inert or active shielding gas (e.g., argon, CO2), delivering high efficiency for thin to medium-gauge materials and ensuring clean, spatter-free welds. For thick-section fabrication, our Submerged Arc Welding (SAW) process—where the arc is submerged in granular flux—enables high deposition rates, deep penetration, and minimal fume, making it ideal for heavy-duty structural work. Additionally, Flux-Cored Arc Welding (FCAW) is a go-to for outdoor or windy conditions, as its tubular flux-cored wire eliminates the need for external shielding gas while providing strong, corrosion-resistant welds.

Quality Policy:

1. Raw Material Control
Sourcing: Cooperate with qualified suppliers ; demand material certificates (e.g., electrode/m wire test reports).
Incoming Checks: Inspect welding materials for expiration dates, packaging integrity; verify base metal dimensions (using measuring tools) and surface conditions (visual checks for rust, cracks).

2. In-Process Control
Pre-Welding Setup: Welders confirm welding procedures (current, voltage, travel speed) match WPS; check equipment (welding machines, clamps) for proper functioning.
Real-Time Checks: Monitor interpass temperature (infrared thermometers), weld bead shape (visual inspection), and root penetration (using ultrasonic testing for critical joints) every 30 minutes.
Documentation: Record welding parameters, inspector comments, and any adjustments made to address issues promptly.

3. Final Inspection
Weld Integrity: non-destructive testing (NDT) including X-ray for internal defects, dye penetrant for surface cracks.
Dimensional Checks: Measure weld dimensions (width, reinforcement) against drawings (using calipers, rulers) with tolerance within ±0.5mm.
Mechanical Tests: Conduct tensile, bend, or impact tests on sample welds from each batch as required.

4. Pre-Shipment Inspection
Batch Sampling: Randomly select welds for rechecking of NDT results and dimensional accuracy.
Surface Treatment: Ensure post-weld treatments (grinding, painting) meet standards; check for burrs, uneven surfaces.
Docs: Attach welding inspection reports, NDT certificates, and material traceability records.

Packing & Delivery

Packing Specs

1. Materials
Outer Packaging: Use sturdy steel-framed crates or fumigated wooden boxes (with certificate) based on product weight.
Inner Protection: Wrap parts with anti-rust film; use foam pads for edges/corners to prevent collision.
Fixing: Secure with steel straps; add braces inside to avoid shifting.

2. Process
Clean surfaces to remove weld spatter and debris.
Wrap with inner materials, place in outer packaging, and fix firmly.
Seal crates/boxes properly.

3. Markings
Product name, model, quantity on visible areas.
Include "Heavy Load", "This Side Up", "Anti-Rust" labels.
Clear destination, consignee info, and shipping marks.
