The proportion of foreign capital for key parts and components of new energy vehicles is not to exceed 50%

Recently, the National Development and Reform Commission and the Ministry of Commerce have revised the "Foreign Investment Industry Guidance Catalogue". The draft of the consultation opinion stated that the proportion of foreign capital for key components of new energy vehicles should not exceed 50%.

This is the first time that the country has clearly defined the joint venture shares of key components of new energy vehicles. This provision may have a profound impact on the entire industrial layout of parts and components of multinational companies in China. A person in charge of an international multi-parts component company stated that this policy will enable a large number of foreign-invested enterprises in China to adjust their share ratios and spread across the board. Because many key parts manufacturing plants in China are not built according to the "no more than 50%" ratio.

Compared with the "Foreign Investment Industry Guidance Catalogue" (2007 revision), this draft of the consultation has added many items related to strategic emerging industries in the encouraged category. In particular, it is worth noting that, in the transportation equipment manufacturing industry, the 2007 version of the catalogue was included in the encouraged category of "automobile manufacturing (less than 50% foreign investment ratio) and the development of automobile R&D institutions" and no longer appeared in the solicitation. Among the encouragement of the drafts.

haracteristics and Applications:

ENiFe-CI is a covered electrode of Fe-Ni alloy core rod with graphite coating. The weld metal provides low expansion coefficient, less hardening and good machining property. It is suitable for ductile cast iron, malleable cast iron and gray cast iron. Satisfied performance can be obtained in the welding of large or high-restraint workpiece. The toughness is higher than that of T-Cast100.

Notes on usage:

1. Clean up the contaminations on the base metal and welding seam so as not to derogate the weld metal quality from crack and porosity.

2. Heat the welding portion to fully evaporate oil, liquor or solvent on it, normally the temperature is at around 400~500℃.

3. Maintaining short arc length as possible is highly recommended. While welding with weave method, moving range should be controlled within 3 times of the wire`s dia.

4. Use intermittent weld and keep arc length short (not longer than 3") or the prolonged heating might cause crack on joint edge. Symmetrical intermittent weld should be applied to multi-layer welding so as to balance the heat stress.

5. Pre-heating and slow cool-down is sometimes required, according to the metal`s type, shape

and size.

6. To alleviate shrinking stress, proceed peening on and off at the temperature above 540℃ after welding to prevent crack or distortion.

.Typical chemical composition of weld metal (wt%):

Welding position:                                                            

Sizes and recommended current range (AC or DC<+>):

Diameter(mm)	2.6	3.2	4
Length(mm)	300	350	350
Amps	60-80	70-120	100-150
