Industry Technical Pain Points: The Efficiency and Precision Dilemma of Traditional Reinforcing Mesh Welding
In large infrastructure projects such as expressway, high-speed railway bridges and tunnels, steel wire mesh, as the core load-bearing structure, its welding quality directly affects the safety and service life of the project. Traditional welding processes rely on manual operation and have three major pain points: Firstly, welding efficiency is low, with a daily output of less than 500 square meters per machine, which is difficult to meet the needs of large-scale construction; secondly, welding accuracy is hard to guarantee, as manual operation often leads to issues like misalignment and false welding, with a defect rate as high as 8%-10%; thirdly, automation level is low, requiring 3-5 operators, with labor costs accounting for over 30% of the total cost. Additionally, traditional equipment has poor adaptability to steel bar specifications, capable only of handling bars with diameters of 6-12mm, and requires mold changes for diameters outside this range, further reducing production flexibility. A bridge and tunnel project once suffered a decrease in the bearing capacity of the mesh due to insufficient welding accuracy, resulting in rework, delays in the construction schedule, and economic losses. How to break through the triple bottleneck of efficiency, accuracy, and automation has become a technical challenge that the industry urgently needs to solve.

FAQ Question and Answer Technical Selection Guide
Q1: How to choose the suitable welding equipment for the steel mesh project?
A: To be evaluated from three aspects:
STEP 1: Production Capacity Requirement——Select daily production capacity of equipment based on project scale (e.g., 1500㎡/day corresponds to XH-HW2000).
STEP 2: Rebar Specifications——Confirm the equipment's supported diameter range (6-25mm) and spacing adjustment capability (50-300mm).
STEP 3: Level of Automation——Prioritize equipment with integrated automatic feeding, cutting, and stacking functions to minimize manual intervention.
Q2: Common causes and solutions for insufficient welding accuracy?
A: Common causes include:
Step 1: Clamp looseRegularly inspect the fixture bolts and maintain the torque value between 50-60N·m.
STEP 2: Welding pressure is unstable——Calibrate the pressure sensor to ensure the welding pressure is within the range of 2000-3000N.
STEP 3: Reinforcement surface oxidation——Scrape the reinforcement surface with a wire brush before welding, and the thickness of the oxide layer should be ≤0.1mm.
Q3: What are the key points to pay attention to in equipment maintenance?
A: Key attention required:
STEP 1: Daily Inspection-Clean welding slag, check servo motor temperature (≤65℃).
STEP 2: Weekly Maintenance——Lubricate guide rail (using lithium-based grease), replace filter element;
STEP 3: Monthly Maintenance—— Calibrate laser positioning system (error ≤0.3mm), inspect electrical component insulation (≥1MΩ).
