H형강이 만들어지는 과정: 공장 둘러보기
Follow the sequence of steel plate cutting, assembly tack welding, gantry submerged-arc welding and flange straightening to understand the tasks undertaken by each machine in the split H-beam production line. It is suitable for customers who are planning an entire line for the first time to first establish a process concept.
Watch highlights
Distinguish between the responsibilities of panel preparation, assembly tack welding and main welding.
Considering the flow of workpieces between workstations, consider the conveying, lifting and buffering areas.
Further confirmation when selectingDo the representative workpieces, daily product mix, and plant length support the same route?
Equipment display of flame and plasma cutting machines, corresponding to steel plate blanking at the front end of H-beam production. You can check the equipment page to learn about the cutting method, cutting torch and power supply configuration, and then choose a solution based on the actual plate thickness and trimming requirements.
Watch highlights
Distinguish the blanking tasks corresponding to flame and plasma configurations.
Connect the cutting results with the board size and trimming status required for subsequent assembly.
Further confirmation when selectingWhat are the main plate grades, thickness range, slitting width and daily cutting volume?
Short clip of the cutting machine undergoing cutting tests after completing on-site installation. Pay attention to the relationship between equipment installation and process verification: After the on-site installation is completed, the test cutting results need to be confirmed according to materials, gases and cutting conditions.
Watch highlights
Understand the relationship between the cutting table, equipment and surrounding work space from the on-site layout.
Consider trial cutting as a verification step before production, and clarify the items to be measured later.
Further confirmation when selectingAre the on-site power supply, air source, smoke exhaust and trial cutting materials ready?
demonstrates the process of aligning, clamping, and tack welding the web and the flange plate to form a stable combination for subsequent main welding. The original video has been accelerated and is suitable for observing the sequence of actions, but not suitable for calculating production capacity based on it.
Watch highlights
Observe the sequence relationship between plate positioning, clamping and tack welding.
Distinguish between tack welding, which maintains the cross-sectional shape, and main welding, which subsequently assumes the joining requirements.
Further confirmation when selectingHow to determine the straightness of incoming materials, tack welding requirements and the positioning method of tapered-section workpieces?
Center around the web and flange plate in H-beam assembly, and understand how the assembly equipment prepares the workpiece for subsequent welding. The cross-sectional size, plate condition and clamping method should be considered when selecting.
Watch highlights
Focus on establishing and maintaining the relative position of the web to the flange.
Check the conventional section, eccentric section and type change requirements based on the equipment parameters.
Further confirmation when selectingIs the workpiece symmetrical, does the cross-section change along the length, and what are the minimum and maximum specifications?
Running demonstration of 1250AC＋1600DC double wire gantry submerged-arc welding configuration. From this, you can understand the relationship between gantry travel and welding configuration, and then choose a single-wire or double-wire solution based on the joint form, weld size and process verification.
Watch highlights
Understand the position of the twin wire configuration in the main longitudinal weld process.
Discuss power combinations, welding speeds, heat input, and joint conditions together.
Further confirmation when selectingFull penetration without beveling or other welding requirements, based on what materials, plate thickness and testing methods should be verified?
Taking double-arc double-wire submerged-arc welding processing H-beam as the theme, showing the welding operation and post-weld pass. The focus of observation is process and appearance inspection; internal quality still needs to be confirmed according to the agreed inspection method.
Watch highlights
Observe the relationship between the welding process, the weld bead after slag removal, and subsequent inspections.
Distinguish between appearance observation, dimensional inspection and internal defect detection.
Further confirmation when selectingAre weld legs, penetration requirements, consumables and non-destructive testing standards defined in the technical agreement?
Field operation demonstration of 60A flange straightening machine to understand the post-weld straightening process. When selecting straightening equipment, you need to consider the flange width, thickness, material and deformation state.
Watch highlights
Understand the corresponding relationship between post-weld flange deformation and straightening process.
Check the arrangements for workpiece support, incoming and outgoing materials and measurements before and after straightening.
Further confirmation when selectingWhat are the materials, yield strengths, flange widths and allowable deviations that require straightening?
The operation fragment of 80B flange straightening equipment can be compared with 60A, 60B, and 80B on the equipment page to understand the selection conditions. Model comparisons should combine workpieces and materials, not just a maximum thickness number.
Watch highlights
Check straightening capability with flange width, thickness and material strength.
Dimensional remeasurement after considering long workpiece support, handling and straightening.
Further confirmation when selectingWhat is the ratio of typical specifications to extreme specifications? Is it necessary to provide test specimens for verification?
A short video showing assembly, welding and straightening integrated into an integrated machine. It is suitable for comparison with the split route to understand the changes in workpiece transportation, work station organization and changeover requirements after the process is centralized.
Watch highlights
Identify the connection of assembly, welding and straightening in the same equipment.
Include workpiece coverage, loading and unloading, and downstream processes in the whole-line comparison.
Further confirmation when selectingAre product cross-section changes, batch structure and welding requirements suitable for the integrated machine route?
Taking the connection of transportation, assembly, welding and straightening as the main line, observe the equipment organization of the H-beam production line. It can be used to discuss how workpieces are handed over between workstations, and what logistics and operating space needs to be reserved in the layout.
Watch highlights
Pay attention to the transportation and handover between processes and the flow direction of workpieces.
Incorporate loading and unloading, changeover, inspection and buffer times into capacity assessment.
Further confirmation when selectingHow do the existing cranes, incoming and outgoing material directions, shifts and work-in-progress areas cooperate with the new production line?
