Tonchel Industries relies on years of experience in metal structure manufacturing and its own casting and CNC precision machining capabilities to provide integrated solutions for non-standard mechanical component welding, cast/cast aluminum welding, dissimilar metal welding, and equipment component welding and repair. Our services cover the entire chain from drawing process review, cutting group matching, welding forming, post weld heat treatment, non-destructive testing to machining and surface protection. We can undertake new batch welding parts, large frame structural parts, and domestic welding transformation of imported spare parts, adapting to the strict load of heavy equipment and foreign trade export quality standards.
1. Weldable materials and product types
1.1 Machinable materials
Carbon steel, low-alloy high-strength steel, stainless steel, manganese steel, chromium molybdenum heat-resistant steel, cast steel parts, aluminum alloy castings (cast aluminum welding), etc
1.2 Core Welding Component Categories
a. Equipment rack, base, crossbeam, support frame, heavy-duty load-bearing bracket
b. Hydraulic/Petroleum Equipment Shell, Valve Body Components, Pipeline Welding Assembly, Fracturing and Cementing Equipment Welding Structural Components
c. Welding and assembly components for wind power, lifting machinery, and woodworking machinery
d. Experimental equipment vacuum chamber, load-bearing platform, sealed welded box body
e. Welding repair of cast steel/cast aluminum blanks, crack repair of castings, welding repair of old equipment components
2. Mainstream welding process
Match welding process based on workpiece material, thickness, load level, and sealing requirements:
MIG/MAG gas shielded welding: High efficiency and controllable deformation for large quantities of structural components.
TIG argon arc welding: for aluminum alloy, stainless steel, thin-walled precision parts, the weld seam is aesthetically pleasing and suitable for sealing components.
Submerged arc welding: Heavy structural components with thick plates, large long welds, deep penetration, and high joint strength.
Manual arc welding: thick and large parts, on-site repair, cast steel and iron repair.
Supporting process: preheating before welding, interlayer temperature control, post weld hydrogen/stress relief annealing, reducing welding residual stress, avoiding cracks, deformation, and fatigue failure.
3. Key application industries (aligned with casting solutions)
3.1 Petroleum equipment: Welding assemblies for fracturing, cementing, and drilling equipment, high-pressure load-bearing welded components, impact resistant and corrosion-resistant working conditions in the field, and non-destructive testing of welds to meet pressure requirements.
3.2 Wind power equipment: Wind power brackets, bases, connecting structural components, high-strength steel welding, controlling welding deformation, and meeting fatigue load requirements.
3.3 Woodworking Machinery: Machine frame, transmission bracket, weight welding components, high-frequency continuous operation, seismic stability.
3.4 Testing and Inspection Equipment: Vacuum Chamber, Mechanical Testing Machine Rack, Sealed Box, Strictly Control Welding Deformation, Ensure Airtightness and Long term Dimensional Stability.
3.5 General heavy-duty machine tools: bed frame, column, large welded base, reduce residual stress, and ensure long-term accuracy of the machine tool.
3.6 Lifting engineering machinery: lifting lugs, load-bearing arms, connecting supports and other load-bearing welded components.
4. Integrated service capability throughout the entire process
Welding+CNC precision machining+heat treatment+surface treatment one-stop delivery
4.1 Preliminary process review: The customer provides drawings/samples, and the engineer conducts weldability analysis, weld seam structure optimization, and welding deformation prediction; For casting welding, assess the risk of base metal cracking in advance, optimize groove and preheating schemes, and reduce scrap rates.
4.2 Cutting and assembly: laser/plasma cutting, bending, machining grooves, fixture positioning and assembly to ensure assembly dimensional accuracy.
4.3 Welding Forming: Manual Welding+Laser Welding Combination; Multi layer and multi pass welding, controlling heat input and reducing deformation.
4.4 Post weld treatment: stress relief annealing, hydrogen removal treatment, polishing, and weld polishing.
4.5 Precision machining: CNC turning, milling, drilling and grinding after welding to ensure dimensional tolerances of assembly holes and mating surfaces.
4.6 Surface protection: sandblasting, primer, topcoat, rust prevention treatment, passivation, suitable for indoor/outdoor corrosive environments.
4.7 Delivery: Single piece sampling, small and medium-sized batch supply, and bulk supply of large structural components.
5. Core advantages of the plan
5.1 Integrated collaboration of casting and welding: self owned casting production+welding processing, matching casting blanks with welding assemblies in the same factory, reducing the size matching risk caused by multiple supplier docking, and shortening delivery time
5.2 Proficient in Welding Difficulties of Castings: Targeting the cracking problems of cast steel, cast aluminum, and cast iron, customized preheating, welding materials, and heat treatment processes can be used to repair cracks in old castings and replace imported spare parts domestically
5.3 Strict control of deformation and fatigue performance: Through tooling, segmented welding, and stress relief heat treatment, the problem of welding deformation in large frames is solved to ensure long-term stable load-bearing, fatigue resistance, and impact resistance of equipment
5.4 Full process traceability, suitable for foreign trade: welder qualifications, welding process qualification WPS/PQR, material certificates, NDT testing reports are complete, supporting export project audits
5.5 Flexible orders: support single sample making, small batch trial production, and large-scale production; Engineers can assist customers in optimizing structures, reducing the number of welds, and lowering welding costs
5.6 Technical after-sales service: Full process technical docking, providing welding process solutions, and providing technical support for the use and maintenance of welded parts after delivery
6. Standard Cooperation Process
Requirement communication → Drawing/sample evaluation&welding process plan review → WPS process preparation → Tooling production+sample welding → Sample testing confirmation → Batch welding production → Post weld heat treatment, polishing → CNC precision machining, surface treatment → Dimensional re inspection and data organization → Packaging delivery → Post sales technical follow-up
