WELDER

DESCRIPTION OF SIGNIFICANT ACTIVITIES

 

1/ Preparation of welding activities:

​

• Take note before intervention: construction plans, maintenance file, constraints (temperature, pressure, mechanical forces), history of interventions, checks to be carried out 

• Make sure to record the installation, QHSE instructions and specific PPE port

• Prepare the work area and the means necessary for the activity:

• (Identify OF and check energy and consumables.) Security/Environment: organize and secure the work area, identify risks and authorizations

• Follow DMOS instructions, read plan and identify welding areas

• Check supply of parts to be positioned and assembled

• Report the missing and defects to the manager

• May be required to assist the Boilermaker in assembling piping sections and supports and assist with ribing

 

2/ The realization of pointing and welding positioning operations  

​

• In case of repair: visual inspection and penetrant techniques before intervention

• Check and Adjust welding parameters (welding station, gas flow rate used, wire speed.)

• Perform the positioning of the elements according to the plan, the docking (degrease, whiten, adjust, grind, point and prepare the joint between the 2 parts to be welded

• Perform welds according to the appropriate processes and applicable standards by anticipating deformations, provide flexibility if necessary for retouching (preparation of parts, preheating, execution of passes, descaling)  

• Check and check the conformity of the weld according to the CDC: visual quality control (welding aspect and geometry of the assembly) or penetrant defect surface with a product =CND

• Report on its activity: fill in the working documents technical sheets of intervention: traceability, anomalies, hazards (quality, time), difficulties, warning points: identification of non-conformities and actions carried out according to instructions , information of quality docs according to company procedures but also proposals for improvements (process, workstation organization ) 

-> save these documents with legal value = proof of compliance with the regulations Fill in the CMMS if existing

 

• Perform service and maintenance of the first level of the welding station (ex change the nozzles of the welding torch, remove the suction filter of the welding station) and order and cleanliness of the workstation and waste management.
