MEDIUM AND HEAVY BOILER
r & d
We do a review of the client’s specifications and a technical review:
Specification of necessary materials
Specification of welding procedures.
Required welding qualifications.
Non-destructive testing (NDT) procedures.
Starting from the customer’s drawings, we break up the complete set.
We carry out all kinds of cuts and assemblies using 3D software tools.
We trace the assembly and welding sequence taking into account the contractions and deformations generated by welding.
level bed mounting
Perpendicularity and parallelism
Accessibility for inspections
Preparation of welding joints
Deformation of welds
At Juan Lasa we carry out the assemblies taking into account the customer’s machining plans.
Previous operations are clearly identified in the documentation generated by our technical department to avoid possible errors. We pay special attention to previous machining operations, the sequence of welds, accessibility, etc.
We always check all the measures and the excesses. We ensure the geometry of the welded part.
Capacity to handle pieces of up to 40Tn.
Qualified Welders and Welding Operators.
We have certified technicians, holders of the CERTIAEND level II certificate, to issue reports in the three types of tests.
100% bond solder joint design
Start and end of welding outside the customer's part
Result: Customer part without impurities
BOILER FINISHES ACCORDING TO CUSTOMER SPECIFICATIONS
Stabilization of welds - Heat treatment
After the stresses generated by welding, we manage their stabilization to eliminate them, using HEAT TREATMENT and VIBRATION STABILIZATION techniques. A graph of the entire process is generated showing the heating, holding and cooling times.
Finishes in Juan Lasa
According to the customer’s specifications, the pieces can undergo finishing processes such as reworking of threads, polishing of machined surfaces, application of industrial grease for surface protection, etc.
Application of primer paints after the shot blasting process to protect the material. The quality and thicknesses applied are those required by the client.
Shot blasting the parts
We apply shot blasting to remove surface impurities from pieces cut from industrial sheet metal and those generated in the manufacturing process. The oxide generated during the heat treatment is removed. Standard ISO 8501-1 Shot blasting Sa 2½.
We offer regular transport services throughout Europe with the best international agencies.
If the client requests that the piece be machined in Juan Lasa, we have a long and close relationship with the best machining companies in the area, offering the best quality-price.
