The identification of the location of the welds is an essential part of the cahier de soudage delivered to the customer during the construction preparation phase.
The identification of the location of the welds should not be confused with the simplified and symbolic representation of the welds (see image 1).Indeed, the welds can be represented on a drawing of a welded assembly following the rules for the establishment of technical drawings standardized by EN ISO 2553 (February 2014).

Namely, most of the technical drawing software have standardized symbol libraries such as ANSI, ISO, GOST and JIS.
However, although this welding symbolism is intended to explain the weld patterns for a given drawing, the location identification is intended to show the customer where the welds in his equipment are located, and is related to elements drawn in the cahier de soudage.
Beforehand, the welds are prepared in a summary table before execution and each one has an identifier (S01, W01 etc.). Then, these identifiers are generally represented by a “bubble” accompanied by an arrow to designate the welded area (see image 2).

In order for the cahier de soudage to be complete (generally speaking and excluding additional technical requirements imposed by the client), each of these welds is marked with a WPS number. Each manufacturing WPS must indicate the reference PQR. And each WPS summarizes the essential parameters for preparing the weld. This association of identification number/welding parameters/DMOS/QMOS poses a serious problem of office automation (marking, WPS writing, PQR scanning, report and welding summary table etc.).
The coordinator then quickly finds himself having to juggle between drawing software, Word, Excel, Paint (?!) in order to obtain the best layout.
It should be noted that technical drawing software is not intended to ensure this layout and traceability of welds in a cahier de soudage.
Sirfull™ Welding frees you from Word, Excel, or anything else in the layout of your cahier de soudage. From a simple import of a manufacturing drawing made on a technical drawing software (in PNG, JPEG, JPG, PDF formats), you have all the tools to locate traced welds in a single solution specifically dedicated to this purpose (see video 1).

From the assembled materials, to the reference PQR, to the welding parameters, each identifier placed on the drawing is linked to a history of information traced and reported to the customer during the automatic generation of the cahier de soudage.
