Engineering notes
Practical guides to cutting, H-beam production and surface preparation, with planning checks you can use on a real project.
These dates show the proposed editorial schedule for this preview; they do not represent previous publication.
Plan H-beam SAW tab materials, fit-up, arc starting and stopping, removal and end inspection around the joint type and approved procedure.
Read article ↗
Set datums, inspect straightness and flange perpendicularity, and record before-and-after measurements for acceptance of welded H-beams.
Read article ↗
Manage flux identification, storage, drying, holding, recovery and fresh-flux additions in longitudinal H-beam submerged arc welding. Follow the actual flux manufacturer and project documents for treatment conditions.
Read the guide ↗
Connect shot blasting, storage and painting with workpiece identity and inspection location. Check cleanliness, contours and specified contaminants separately, record release status, and verify that the surface has not failed before painting.
Read the guide ↗
Calculate the entire line load using product mix, complete station cycle, and shared resources. Distinguish the welding speed, machine idling speed and qualified finished product output, and then decide how to match the equipment.
Read the guide ↗
Being able to cut it does not mean that it can be assembled directly. Use first article inspections, process reviews, and clear handover records to proactively identify cutting issues that could cause welding, hole placement, or assembly rework.
Read the guide ↗
The main chamber, abrasive circulation and dust removal together determine whether the equipment can continue to operate. Check the supply boundary along the material and air flow paths, and then establish records of abnormality investigation, shutdown maintenance and commissioning handover.
Read the guide ↗
The plane layout should simultaneously solve the long beam incoming and outgoing materials, turning, overhead crane scheduling, buffering and maintenance. Only through layer-by-layer review based on workpiece paths and on-site interfaces can the equipment list be transformed into an installable and producible solution.
Read the guide ↗
Section steel cutting must cover both long beam sections and meet specific requirements for connecting holes, openings and ends. When selecting TW-LHC, the workpiece reference, hot-heated hole quality and subsequent assembly should be checked together.
Read the guide ↗
The blast wheel total does not alone indicate cleaning quality or yield. Compare the layout, loading, action time and supporting systems around the web, inside the flange and attachment shadow area, and confirm coverage with representative workpieces.
Read the guide ↗
Distinguish the full penetration without beveling of single wire 16 mm and double wire 24 mm, and the applicable conditions of beveling, multi-layer, multi-pass welding; combined with the 14 mm upper limit of the light steel integrated machine, real joints and inspection requirements to determine the configuration.

12–60 kW is the optional power range only. Define your production goals with actual materials, piercing and slotting tasks, then compare the complete package of a Raycus or Maxphotonics laser with a Bochu system and cutting head.
Read the guide ↗Abrasives affect cleaning performance, surface profile and operating costs. Separately manage new material specifications and working mixtures in the cycle, and then use surface results, screening records and separation status to verify adjustments.
Read the guide ↗
From incoming material matching, positioning and pressing to tack welding and release, a repeatable cross-section benchmark is established. Combined with the TW-HAM model range, special beam type and process handover, assembly problems are reduced and left to the main welding station.
Read the guide ↗
Nesting is not about arranging graphics as densely as possible. Material grouping, cutting sequence, part identification and complete set output jointly determine the actual efficiency of steel structure supporting panels.
Read the guide ↗Determine the shot blasting configuration from the actual workpiece envelope, surface requirements and conveying method. 1220, 1225 and 2050 are common models. Check the custom opening and blast-wheel count against both loading and coverage requirements.
Read the guide ↗
The flange straightening capability shall be reviewed based on the actual cross-section combination. Compare the independent ranges of TW-HSM60A, TW-HSM60B and TW-HSM80B while confirming deformation type, support and measurement method.
Read the guide ↗Long straight strips, profiles with multiple holes and thick plate cuttings place different requirements on equipment. Taking the combined configuration of TW-PQC4000 as an example, the division of labor of the cutting torch is clearly defined, and the target workpiece is then used to verify the output and quality.
Read the guide ↗
shot blasting is not just about brightening the steel. First distinguish between cleanliness, roughness and contaminant control, and then arrange for post-weld treatment, workpiece shielding inspection and trial run of representative parts to form an acceptable surface preparation plan.
Read the guide ↗
The split production line uses flat-position fillet welding to serve heavy steel structures, and the integrated machine uses 45° fillet welding to organize light steel production. First check the web full penetration requirements, and then compare the production capacity organization, employment, plant length and investment.

Web plate strip cutting, support plate nesting and forming beam hole slot processing are three different types of tasks. Separating raw materials, processing characteristics and delivery status can avoid duplication of purchases or missing processes.
