Laser Mold 10

1.4718

(X45CrSi9-3)

Cutting-, draw-, folding-press tools e.g. edges- and surfaces application 1.2379, 1.2363, SKDII, HPM31, GGG70L, GG25, Z160CDV12, DC53, SKH51, Vanadis23, Vanadis30, ASP23, ASP30, Toolox33

Yes

Ca. 55 – 60 HRC

(depends on the laser parameter adjustment). Laser Mold 10 designs hot cracks.

Repairing of incejtion molds e.g. from the named alloys we recommend use alternatively Laser Mold 90, which enables the welder to have a crackfree buildup welding.

Laser Mold

10 PLUS

1.3348

(HS2-9-2)

Laser Mold 10PLUS can be applied without problems with 1.2379, 1.2363, 1.2080, SKDII, HPM31, GGG70L, GG25, DC53, SKH 51, Z160CDV12, Vanadis 23, Vanadis 30, ASP 23, ASP 30, Toolox33 directly and crack free on fine edges (maximum height 0,50 mm)

Yes

60 – 65 HRC

Free of cracks laser weldings can only be obtained without any problems when the tool is preheated on a temperature of 80°C - 100°C. If it is not preheated there will be spontaneously formed W-carbides which are non-reversible. ?aser Mold® 10 PLUS can

be used with a powerful laser welding unit e.g. Pulspower 300 Watt up to wire size of

0,60 mm. For ?aser Mold® 10 PLUS a pulse time of at least 10 ms should be adjusted.

If there is a big welding volume needed an interface layer with ?aser Mold® 10 PLUS is

recommended. (At least 2/3 of the welding bath height needed.)

To guarantee a free of cracks welding the welding volume of ?aser Mold® 10 PLUS

needed should not exceed 0,5 mm of the welding height.

or radii.

If cracks which are caused by a fire are going to be repaired ?aser Mold® 60 should be

premelted as an interface layer. ?aser Mold® 55 is very flexible concerning the

adjustment of the pulse time. If pulse times of more than 8 ms are used it can possibly

be worked without protective gas. If repairs in mirror finish areas are made use less

than 4.5 ms.

Laser Mold 60

X10CrMo6-3

Mold and Tool

Special welding additive for bubbles and porosities on aluminium castings. When the material is welded the principle of diffusion is used, like it is originally used when soldering.

When applying with laser welding there is a combination of melting and diffusing.

?aser Alu Sint 380 Mold and tool distinguishes by a high absorption of the laser beam, that is the reason why the parameters should be adjusted like follows: little pulse power (Kw = little voltage) and high pulse energy (Joule = long pulse times).

The focus diameter of the laser beam will be highly defocused so that the basic material

will heat up and when adding ?aser Alu Mold 380 Mold and Tool a welding process of the welding additive will start immediately which is diffusing into the basic material at the same time.

Preheating of the component on about 80° C elevates the quality of the connection.
