1. The Power of Tandem SAW: High Productivity & Quality

Submerged Arc Welding (SAW) is a highly efficient welding process, particularly suited for thick materials and long, continuous welds. Tandem SAW takes this a step further by using two independent welding wires (lead and trail) fed into a single molten pool, significantly increasing welding speed and deposition rates. This means fewer passes, faster completion times, and superior weld quality compared to single-wire SAW or other processes.

1.1. Common Materials & Thickness Range in India:

This integrated system excels in heavy fabrication for the same materials suited for Tandem SAW:

• Mild Steel & Low Alloy Steels (e.g., IS 2062 Grade B, ASTM A36): Typically 8 mm to 100 mm and above.
• Boiler Quality Plates (e.g., IS 2002, SA 516 Gr. 70): 10 mm to 150 mm and beyond.
• High Strength Low Alloy (HSLA) Steels: 8 mm to 50 mm.

2. McLease H-BEAM MASTER PRO: Machine Specifications

The H-BEAM MASTER PRO is configured for high-performance and reliable operation, designed for H/T beams up to 12 meters long with a 6-meter width access, all within a unified system.

2.1. Core Integrated System Components (Leveraging Shared Gantry):

• Multi-Functional Gantry Structure:
  • Description: A single, robust, heavy-duty gantry, precision-engineered to act as the universal motion backbone for multiple processes.
  • Working Area: Designed to cover workpieces up to 12 meters (length) x 6 meters (width).
  • Movement: Motorized longitudinal travel along ground rails (for 12m length), motorized cross-travel of the trolley along the gantry bridge (for 6m width), and motorized vertical lift/lower of the various process heads.
  • Structure Material: Heavy-duty fabricated steel sections, precision machined.
  • Precision Motion Components: Utilizes high-performance AC Servo motors, high-accuracy linear guide rails, and precision gear racks & pinions for smooth, precise, and powerful movement across all axes.
• Integrated H-Beam Assembly & MIG Welding (Tack Welding) Heads:
  • Function: Mounted on the shared gantry, these heads perform the precise alignment and synchronized hydraulic clamping of the web and flange plates.
  • Welding Process: MIG tack welding with programmable time-based weld/skip settings for initial joint integrity.
• Integrated Tandem SAW Welding System (The Powerhouse Welder):
  • Function: Mounted on the same multi-functional gantry, this is a 1200 Amps Tandem SAW system (two independent welding wires: Lead DC, Trail AC) that performs the main, high-deposition fillet welds joining the web to the flanges.
  • Flux Management: Includes a large capacity heated flux hopper, automatic feeding, and integrated vacuum-type flux recovery.
  • Key Features: Automatic Arc Voltage Control (AVC), motorized cross slide for precise torch positioning, and capability for high welding speeds (e.g., 20-150 cm/min).
• [Optional] Integrated CNC Drilling Head:
  • Function: A drilling spindle can be mounted on the same gantry, allowing automated hole drilling on the H-beams.
• [Optional] Integrated CNC Plasma-OxyFuel Cutting Machine:
  • Function: For ultimate versatility, a Plasma and/or Oxy-Fuel torch cutting station can be integrated onto the gantry, allowing precise profile cutting of plates (for flanges/webs or other parts) before or after H-beam assembly, all on the same system.
• Intelligent Control System:
  • System: A single, central CNC/PLC control panel with an intuitive HMI manages and synchronizes all integrated processes (gantry movement, assembly clamping, tack welding, Tandem SAW parameters, CNC drilling, Plasma-OxyFuel cutting, etc.).
  • Parameter Storage: Ability to store and recall comprehensive production and welding programs.

2.2. Standalone Hydraulic Flange Straightening Machine (Post-Process):

• Important Note: The final Hydraulic Flange Straightening Machine is typically a separate, standalone unit. This is due to the immense forces required to correct heat-induced deformation in welded H-beam flanges.
• Operation: A powerful hydraulic machine with hardened alloy steel straightening wheels and drive rollers precisely restores flange linearity. The welded H-beam is transferred from the gantry's working area to this machine for the final straightening step.

2.3. Welding Quality Standards (Common in India):

The system is designed to help you achieve welds compliant with: IS 4353, AWS D1.1/D1.1M, ASME Boiler and Pressure Vessel Code (Section IX), and NABL Accreditation for testing.

2.4. Typical Welding Speed:

With the 1200 Ampere tandem SAW system integrated, welding speeds for H-beam seams vary:

• For thinner sections (e.g., 8-15mm): 80-150 cm/min.
• For medium sections (e.g., 16-40mm): 40-80 cm/min.
• For thick sections (e.g., 40-100mm+): 20-50 cm/min per pass.

3. Operational Advantages & Benefits

The McLease H-BEAM MASTER PRO offers profound operational advantages:

• Reduced Capital Investment: Avoids the significant cost of separate gantries and control systems for each process.
• Optimized Factory Footprint: Consolidates multiple processes onto one platform, saving valuable floor space.
• Streamlined Production Workflow: Minimizes material handling between assembly, tack welding, main SAW welding, drilling, and cutting by performing these sequential operations under a single gantry.
