The colibri tweezers are a high-precision surgical instrument. We will show you how such tweezers can be welded using our high-precision micro TIG welding process. Other surgical instruments and tools can also be welded in the same way – with minimal heat input and minimal structural changes. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The holes to be welded must first of all be cleaned of dirt and grease. The spacer pins are inserted precisely into the holes provided until they are flush with the outside of the tweezers part. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The pins are welded flush to the outside of the tweezers using several welding points. A medium power setting and a pulse duration of 4-5 ms on the Micro Arc Welder<\/a> are sufficient.

If necessary, the weld seam can be trimmed and ground smooth after welding. As a rule, however, reworking is not necessary. <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

After welding, only the dimensional accuracy and the distance of the pins from the tweezers need to be checked. The weld seam itself is not visible on the inside of the tweezers on the spacer pins. Discoloration or other optical impairments of the material are also ruled out with the micro TIG welding process. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The two halves of the tweezers are welded flush with each other at medium power level and approx. 5-6 ms pulse duration of the Micro Arc Welder<\/a>. If the welding points overlap cleanly, subsequent reworking is not necessary. However, for a perfectly smooth surface, it is advisable to grind and polish the weld seam afterwards. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
